Indian Rebellion of 1857
The Indian Rebellion of 1857 was a major, but unsuccessful, uprising in India in 1857–58 against the rule of the British East India Company, which functioned as a sovereign power on behalf of the British Crown. The rebellion began on 10 May 1857 in the form of a mutiny of sepoys of the Company's army in the garrison town of Meerut, 40 miles northeast of Delhi, it erupted into other mutinies and civilian rebellions chiefly in the upper Gangetic plain and central India, though incidents of revolt occurred farther north and east. The rebellion posed a considerable threat to British power in that region, was contained only with the rebels' defeat in Gwalior on 20 June 1858. On 1 November 1858, the British granted amnesty to all rebels not involved in murder, though they did not declare the hostilities formally to have ended until 8 July 1859; the rebellion is known by many names, including the Sepoy Mutiny, the Indian Mutiny, the Great Rebellion, the Revolt of 1857, the Indian Insurrection, the First War of Independence.
The Indian rebellion was fed by resentments born of diverse perceptions, including invasive British-style social reforms, harsh land taxes, summary treatment of some rich landowners and princes, as well as skepticism about the improvements brought about by British rule. Many Indians rose against the British. Violence, which sometimes betrayed exceptional cruelty, was inflicted on both sides, on British officers, civilians, including women and children, by the rebels, on the rebels, their supporters, including sometimes entire villages, by British reprisals. After the outbreak of the mutiny in Meerut, the rebels quickly reached Delhi, whose 81-year-old Mughal ruler, Bahadur Shah Zafar, they declared the Emperor of Hindustan. Soon, the rebels had captured large tracts of the North-Western Provinces and Awadh; the East India Company's response came as well. With help from reinforcements, Kanpur was retaken by mid-July 1857, Delhi by the end of September. However, it took the remainder of 1857 and the better part of 1858 for the rebellion to be suppressed in Jhansi and the Awadh countryside.
Other regions of Company controlled India—Bengal province, the Bombay Presidency, the Madras Presidency—remained calm. In the Punjab, the Sikh princes crucially helped the British by providing support; the large princely states, Mysore and Kashmir, as well as the smaller ones of Rajputana, did not join the rebellion, serving the British, in the Governor-General Lord Canning's words, as "breakwaters in a storm."In some regions, most notably in Awadh, the rebellion took on the attributes of a patriotic revolt against European presence. However, the rebel leaders proclaimed no articles of faith. So, the rebellion proved to be an important watershed in Indian- and British Empire history, it led to the dissolution of the East India Company, forced the British to reorganize the army, the financial system, the administration in India, through passage of the Government of India Act 1858. India was thereafter administered directly by the British government in the new British Raj. On 1 November 1858, Queen Victoria issued a proclamation to Indians, which while lacking the authority of a constitutional provision, promised rights similar to those of other British subjects.
In the following decades, when admission to these rights was not always forthcoming, Indians were to pointedly refer to the Queen's proclamation in growing avowals of a new nationalism. Although the British East India Company had established a presence in India as far back as 1612, earlier administered the factory areas established for trading purposes, its victory in the Battle of Plassey in 1757 marked the beginning of its firm foothold in eastern India; the victory was consolidated in 1764 at the Battle of Buxar, when the East India Company army defeated Mughal Emperor Shah Alam II. After his defeat, the emperor granted the Company the right to the "collection of Revenue" in the provinces of Bengal, known as "Diwani" to the Company; the Company soon expanded its territories around its bases in Madras. In 1806, the Vellore Mutiny was sparked by new uniform regulations that created resentment amongst both Hindu and Muslim sepoys. After the turn of the 19th century, Governor-General Wellesley began what became two decades of accelerated expansion of Company territories.
This was achieved either by subsidiary alliances between the Company and local rulers or by direct military annexation. The subsidiary alliances created the princely states of the Muslim nawabs. Punjab, North-West Frontier Province, Kashmir were annexed after the Second Anglo-Sikh War in 1849; the border dispute between Nepal and British India, which sharpened after 1801, had caused the Anglo-Nepalese War of 1814–16 and brought the defeated Gurkhas under British influence. In 1854, Berar was annexed, the state of Oudh was added two years later. For practical purposes, the Company was the government of much of India; the Indian Rebellion of 1857 occurred as the result of an accumulation of factors over time, rather than any single event. The sepoys were Indian soldiers who were recruited into the Company's army
South Carolina is a state in the Southeastern United States and the easternmost of the Deep South. It is bordered to the north by North Carolina, to the southeast by the Atlantic Ocean, to the southwest by Georgia across the Savannah River. South Carolina became the eighth state to ratify the U. S. Constitution on May 23, 1788. South Carolina became the first state to vote in favor of secession from the Union on December 20, 1860. After the American Civil War, it was readmitted into the United States on June 25, 1868. South Carolina is the 40th most extensive and 23rd most populous U. S. state. Its GDP as of 2013 was $183.6 billion, with an annual growth rate of 3.13%. South Carolina is composed of 46 counties; the capital is Columbia with a 2017 population of 133,114. The Greenville-Anderson-Mauldin metropolitan area is the largest in the state, with a 2017 population estimate of 895,923. South Carolina is named in honor of King Charles I of England, who first formed the English colony, with Carolus being Latin for "Charles".
South Carolina is known for its 187 miles of coastline, beautiful lush gardens, historic sites and Southern plantations, colonial and European cultures, its growing economic development. The state can be divided into three geographic areas. From east to west: the Atlantic coastal plain, the Piedmont, the Blue Ridge Mountains. Locally, the coastal plain is referred to the other two regions as Upstate; the Atlantic Coastal Plain makes up two-thirds of the state. Its eastern border is a chain of tidal and barrier islands; the border between the low country and the up country is defined by the Atlantic Seaboard fall line, which marks the limit of navigable rivers. The state's coastline contains many salt marshes and estuaries, as well as natural ports such as Georgetown and Charleston. An unusual feature of the coastal plain is a large number of Carolina bays, the origins of which are uncertain; the bays tend to be oval. The terrain is flat and the soil is composed of recent sediments such as sand and clay.
Areas with better drainage make excellent farmland. The natural areas of the coastal plain are part of the Middle Atlantic coastal forests ecoregion. Just west of the coastal plain is the Sandhills region; the Sandhills are remnants of coastal dunes from a time when the land was sunken or the oceans were higher. The Upstate region contains the roots of an eroded mountain chain, it is hilly, with thin, stony clay soils, contains few areas suitable for farming. Much of the Piedmont was once farmed. Due to the changing economics of farming, much of the land is now reforested in Loblolly pine for the lumber industry; these forests are part of the Southeastern mixed forests ecoregion. At the southeastern edge of the Piedmont is the fall line, where rivers drop to the coastal plain; the fall line was an important early source of water power. Mills built to harness this resource encouraged the growth of several cities, including the capital, Columbia; the larger rivers are navigable up to the fall line. The northwestern part of the Piedmont is known as the Foothills.
The Cherokee Parkway is a scenic driving route through this area. This is. Highest in elevation is the Blue Ridge Region, containing an escarpment of the Blue Ridge Mountains, which continue into North Carolina and Georgia, as part of the southern Appalachian Mountains. Sassafras Mountain, South Carolina's highest point at 3,560 feet, is in this area. In this area is Caesars Head State Park; the environment here is that of the Appalachian-Blue Ridge forests ecoregion. The Chattooga River, on the border between South Carolina and Georgia, is a favorite whitewater rafting destination. South Carolina has several major lakes covering over 683 square miles. All major lakes in South Carolina are man-made; the following are the lakes listed by size. Lake Marion 110,000 acres Lake Strom Thurmond 71,100 acres Lake Moultrie 60,000 acres Lake Hartwell 56,000 acres Lake Murray 50,000 acres Russell Lake 26,650 acres Lake Keowee 18,372 acres Lake Wylie 13,400 acres Lake Wateree 13,250 acres Lake Greenwood 11,400 acres Lake Jocassee 7,500 acres Lake Bowen Earthquakes in South Carolina demonstrate the greatest frequency along the central coastline of the state, in the Charleston area.
South Carolina averages 10–15 earthquakes a year below magnitude 3. The Charleston Earthquake of 1886 was the largest quake to hit the Southeastern United States; this 7.2 magnitude earthquake destroyed much of the city. Faults in this region are difficult to study at the surface due to thick sedimentation on top of them. Many of the ancient faults are within plates rather than along plate boundaries. South Carolina has a humid subtropical climate, although high-elevation areas in the Upstate area have fewer subtropical characteristics than areas on the Atlantic coastline. In the summer, South Carolina is hot and humid, with daytime temperatures averaging between 86–93 °F in most of the state and overnight lows averaging 70–75 °F on the coast and from 66–73 °F inland. Winter temperatures are much less uniform in South Carolina. Coastal areas of the state have mild winters, with high temperatures approaching an average of 60 °F and overnight lows around 40 °F. Inland, the average January overnight low is around 32 °F i
Cannabis indica, formally known as Cannabis sativa forma indica, is an annual plant in the Cannabaceae family originating from the Indian subcontinent. It is a putative species of the genus Cannabis. Whether it and Cannabis sativa are separate species is a matter of debate. Many uses come from Cannabis indica, such as extraction, cloth from the fibers, medical uses, a plant. Cannabis indica produces large amounts of tetrahydrocannabinol; the large amounts of THC makes it most used as a drug, whether it be for recreational or medical purposes. In 1785, Jean-Baptiste Lamarck published a description of a second species of Cannabis, which he named Cannabis indica as Cannibis that grows in and around India. Lamarck based his description of the newly named species on plant specimens collected in India. Richard Evans Schultes described C. indica as short and densely branched, whereas C. sativa was described as tall and laxly branched. Loran C. Anderson described C. indica plants as having short, broad leaflets whereas those of C. sativa were characterized as long and narrow.
Cannabis indica plants conforming to Schultes's and Anderson's descriptions may have been able to flourish across the Indo-Gangetic Plain. This is because of the harsh and variable climate of those parts, C. indica is well-suited for cultivation in temperate climates. Broad-leafed Cannabis indica plants in South Asia are traditionally cultivated for the production of charas, a form of hashish. Pharmacologically, C. indica landraces tend to have a less THC content than C. sativa strains Some users report more of a "stoned" feeling and less of a "high" from C. indica when compared to C. sativa. The Cannabis indica high is referred to as a "body buzz" and has beneficial properties such as pain relief in addition to being an effective treatment for insomnia and an anxiolytic, as opposed to sativa's more common reports of a cerebral and energetic high, albeit comprising hallucinations. Differences in the terpenoid content of the essential oil may account for some of these differences in effect. Common indica strains for recreational or medicinal use include Northern Lights.
A recent genetic analysis included both the narrow-leaflet and wide-leaflet drug "biotypes" under C. indica, as well as southern and eastern Asian hemp landraces and wild Himalayan populations. There are several key differences between Cannabis indica and Cannabis sativa; these include height and stature, internodal length, leaf size and structure, buds size and density, flowering time, odour and effects. Indica plants tend to grow bushier than the sativa plants. Indica strains tend to have wide, short leaves with short wide blades, whereas sativa strains have long leaves with thin long blades; the buds of indica strains tend to be wide and bulky, while sativa strains are to be long, sausage shaped flowers. On average, Cannabis indica has higher levels of THC compared to CBD, whereas Cannabis sativa has lower levels of THC to CBD. However, huge variability exists within either species. A 2015 study shows the average THC content of the most popular herbal cannabis products in the Netherlands has decreased since 2005.
In the recent era of cannabis breeding higher-ratio CBD strains are being developed from Indica origins that may test out as 1:1 or as high as a 22:1. The medical interests in Cannabis are taking this further and we will see increasing cultivation trends for more strains developed with CBD-dominant ratios. In California, cities such as Coachella and Desert Hot Springs are re-zoning areas for cannabis cultivation. Though Californians legalized recreational use of cannabis in late 2016, the LA Times, prior to the vote, reported an entrepreneurial focus on CBD-dominant medical hemp crops, "The demand for medical products was so high, this was just to fill the need for that." Low anxiety and hallucinogenic properties make these "high-CBD strains" desirable for chronic treatment programs. There are three chemotaxonomic types of Cannabis: one with high levels of THC, one, more fibrous and has higher levels of CBD, one, an intermediate between the two. Cannabis strains with CBD:THC ratios above 5:2 are to be more relaxing and produce less anxiety than vice versa.
This may be due to CBD's antagonistic effects at the cannabinoid receptors, compared to THC's partial agonist effect. CBD is a 5-HT1A receptor agonist, which may contribute to an anxiolytic-content effect; the effects of sativa are well known for its cerebral high. Users can expect a more vivid and uplifting high, while indica is well known for its sedative effects which some prefer for night time use. Indica possesses a more calming and numbing experience in which can be used to relax or relieve pain. Both types are used as medical cannabis. During the 1970s, Cannabis indica strains from Afghanistan and Hindu Kush were brought to the United States, where the first hybrids with Cannabis sativa plants from equatorial areas were developed spreading marijuana cultivation throughout the States. Plants with elevated levels of propyl cannabinoids, including tetrahydrocannabivarin, have been found in populations of Cannabis indica from China, Nepal, Thailand and Pakistan, as well as southern and wes
Indigenous peoples of the Americas
The indigenous peoples of the Americas are the Pre-Columbian peoples of North and South America and their descendants. Although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many in the Amazon basin, still are—many groups practiced aquaculture and agriculture; the impact of their agricultural endowment to the world is a testament to their time and work in reshaping and cultivating the flora indigenous to the Americas. Although some societies depended on agriculture, others practiced a mix of farming and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, city-states, states and empires. Among these are the Aztec and Maya states that until the 16th century were among the most politically and advanced nations in the world, they had a vast knowledge of engineering, mathematics, writing, medicine and irrigation, mining and goldsmithing. Many parts of the Americas are still populated by indigenous peoples.
At least a thousand different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Guaraní, Mayan languages and Nahuatl, count their speakers in millions. Many maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization and subsistence practices. Like most cultures, over time, cultures specific to many indigenous peoples have evolved to incorporate traditional aspects but cater to modern needs; some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples. Indigenous peoples of the United States are known as Native Americans or American Indians and Alaska Natives. Application of the term "Indian" originated with Christopher Columbus, who, in his search for India, thought that he had arrived in the East Indies; those islands came to be known as the "West Indies", a name still used. This led to the blanket term "Indies" and "Indians" for the indigenous inhabitants, which implied some kind of racial or cultural unity among the indigenous peoples of the Americas.
This unifying concept, codified in law and politics, was not accepted by the myriad groups of indigenous peoples themselves, but has since been embraced or tolerated, by many over the last two centuries. Though the term "Indian" does not include the culturally and linguistically distinct indigenous peoples of the Arctic regions of the Americas—such as the Aleuts, Inuit or Yupik peoples, who entered the continent as a second more recent wave of migration several thousand years before and have much more recent genetic and cultural commonalities with the aboriginal peoples of the Asiatic Arctic Russian Far East—these groups are nonetheless considered "indigenous peoples of the Americas". Indigenous peoples are known in Canada as Aboriginal peoples, which includes not only First Nations and Arctic Inuit, but the minority population of First Nations-European mixed race Métis people who identify culturally and ethnically with indigenous peoplehood; this is contrasted, for instance, to the American Indian-European mixed race mestizos of Hispanic America who, with their larger population, identify as a new ethnic group distinct from both Europeans and Indigenous Americans, but still considering themselves a subset of the European-derived Hispanic or Brazilian peoplehood in culture and ethnicity.
The term Amerindian and its cognates find preferred use in scientific contexts and in Quebec, the Guianas and the English-speaking Caribbean. Indígenas or pueblos indígenas is a common term in Spanish-speaking countries and pueblos nativos or nativos may be heard, while aborigen is used in Argentina and pueblos originarios is common in Chile. In Brazil, indígenas or povos indígenas are common if formal-sounding designations, while índio is still the more often-heard term and aborígene and nativo being used in Amerindian-specific contexts; the Spanish and Portuguese equivalents to Indian could be used to mean any hunter-gatherer or full-blooded Indigenous person to continents other than Europe or Africa—for example, indios filipinos. The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, are the subject of ongoing research and discussion. According to archaeological and genetic evidence and South America were the last continents in the world to gain human habitation.
During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the land bridge of Beringia that joined Siberia to northwest North America. Alaska was a glacial refugium; the Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska for thousands of years. Indigenous genetic studies suggest that the first inhabitants of the Americas share a single ancestral population, one that developed in isolation, conjectured to be Beringia; the isolat
Zimbabwe the Republic of Zimbabwe, is a landlocked country located in southern Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa, Botswana and Mozambique. The capital and largest city is Harare. A country of 16 million people, Zimbabwe has 16 official languages, with English and Ndebele the most used. Since the 11th century, present-day Zimbabwe has been the site of several organised states and kingdoms as well as a major route for migration and trade; the British South Africa Company of Cecil Rhodes first demarcated the present territory during the 1890s. In 1965, the conservative white minority government unilaterally declared independence as Rhodesia; the state endured a 15-year guerrilla war with black nationalist forces. Zimbabwe joined the Commonwealth of Nations, from which it was suspended in 2002 for breaches of international law by its then-government, from which it withdrew in December 2003; the sovereign state is a member of the United Nations, the Southern African Development Community, the African Union, the Common Market for Eastern and Southern Africa.
It was once known as the "Jewel of Africa" for its prosperity under the former Rhodesian administration. Robert Mugabe became Prime Minister of Zimbabwe in 1980, when his ZANU-PF party won the elections following the end of white minority rule. Under Mugabe's authoritarian regime, the state security apparatus dominated the country and was responsible for widespread human rights violations. Mugabe maintained the revolutionary socialist rhetoric of the Cold War era, blaming Zimbabwe's economic woes on conspiring Western capitalist countries. Contemporary African political leaders were reluctant to criticise Mugabe, burnished by his anti-imperialist credentials, though Archbishop Desmond Tutu called him "a cartoon figure of an archetypal African dictator"; the country has been in economic decline since the 1990s, experiencing several crashes and hyperinflation along the way. On 15 November 2017, in the wake of over a year of protests against his government as well as Zimbabwe's declining economy, Mugabe was placed under house arrest by the country's national army in a coup d'état.
On 19 November 2017, ZANU-PF sacked Robert Mugabe as party leader and appointed former Vice President Emmerson Mnangagwa in his place. On 21 November 2017, Mugabe tendered his resignation prior to impeachment proceedings being completed. On 30 July 2018 Zimbabwe held its general elections, won by the ZANU-PF party led by Emmerson Mnangagwa. Nelson Chamisa, leading the main opposition party MDC Alliance contested the election results and filed a petition to the Constitution Court of Zimbabwe; the court confirmed Mnangagwa's victory. The name "Zimbabwe" stems from a Shona term for Great Zimbabwe, an ancient ruined city in the country's south-east whose remains are now a protected site. Two different theories address the origin of the word. Many sources hold that "Zimbabwe" derives from dzimba-dza-mabwe, translated from the Karanga dialect of Shona as "houses of stones"; the Karanga-speaking Shona people live around Great Zimbabwe in the modern-day province of Masvingo. Archaeologist Peter Garlake claims that "Zimbabwe" represents a contracted form of dzimba-hwe, which means "venerated houses" in the Zezuru dialect of Shona and references chiefs' houses or graves.
Zimbabwe was known as Southern Rhodesia and Zimbabwe Rhodesia. The first recorded use of "Zimbabwe" as a term of national reference dates from 1960 as a coinage by the black nationalist Michael Mawema, whose Zimbabwe National Party became the first to use the name in 1961; the term "Rhodesia"—derived from the surname of Cecil Rhodes, the primary instigator of British colonisation of the territory during the late 19th century—was perceived by African nationalists as inappropriate because of its colonial origin and connotations. According to Mawema, black nationalists held a meeting in 1960 to choose an alternative name for the country, proposing names such as "Matshobana" and "Monomotapa" before his suggestion, "Zimbabwe", prevailed. A further alternative, put forward by nationalists in Matabeleland, had been "Matopos", referring to the Matopos Hills to the south of Bulawayo, it was unclear how the chosen term was to be used—a letter written by Mawema in 1961 refers to "Zimbabweland" — but "Zimbabwe" was sufficiently established by 1962 to become the preferred term of the black nationalist movement.
In a 2001 interview, black nationalist Edson Zvobgo recalled that Mawema mentioned the name during a political rally, "and it caught hold, and, that". The black nationalist factions subsequently used the name during the Second Chimurenga campaigns against the Rhodesian government during the Rhodesian Bush War of 1964–1979. Major factions in this camp included the Zimbabwe African National Union, the Zimbabwe African People's Union. Archaeological records date human settlement of present-day Zimbabwe to at least 100,000 years ago; the earliest known inhabitants were San people, who left behind arrowheads and cave paintings. The first Bantu-speaking farmers arrived during the Bantu expansion around 2000 years ago. Societies speaking proto-Shona languages fir
In biology, a hermaphrodite is an organism that has complete or partial reproductive organs and produces gametes associated with both male and female sexes. Many taxonomic groups of animals do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the "female" or "male." For example, the great majority of tunicates, pulmonate snails, opisthobranch snails and slugs are hermaphrodites. Hermaphroditism is found in some fish species and to a lesser degree in other vertebrates. Most plants are hermaphrodites; the term hermaphrodite has been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species human beings. The word intersex has come into preferred usage for humans, since the word hermaphrodite is considered to be misleading and stigmatizing, as well as "scientifically specious and clinically problematic."A rough estimate of the number of hermaphroditic animal species is 65,000.
The percentage of animal species that are hermaphroditic is about 5%.. Most hermaphroditic species exhibit some degree of self-fertilization; the distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar processes are operating to direct the evolution of selfing in animals and plants. The term derives from the Latin: hermaphroditus, from Ancient Greek: ἑρμαφρόδιτος, translit. Hermaphroditos, which derives from Hermaphroditus, the son of Hermes and Aphrodite in Greek mythology. According to Ovid, he fused with the nymph Salmacis resulting in one individual possessing physical traits of male and female sexes; the word hermaphrodite entered the English lexicon as early as the late fourteenth century. Alexander ab Alexandro stated, using the term hermaphrodite, that the people who bore the sexes of both man and woman were regarded by the Athenians and the Romans as monsters, thrown into the sea at Athens and into the Tiber at Rome. Sequential hermaphrodites occur in species in which the individual is born as one sex, but can change into the opposite sex.
This contrasts simultaneous hermaphrodites, in which an individual may possess functional male and female genitalia. Sequential hermaphroditism is common in fish and many gastropods, some flowering plants. Sequential hermaphrodites can only change sex once. Sequential hermaphroditism can best be understood in terms of behavioral ecology and evolutionary life history theory, as described in the size-advantage mode first proposed by Michael T. Ghiselin which states that if an individual of a certain sex could increase its reproductive success after reaching a certain size, it would be to their advantage to switch to that sex. Sequential hermaphrodites can be divided into three broad categories: Protandry: Where an organism is born as a male, changes sex to a female. Example: The clownfish are colorful reef fish found living in symbiosis with sea anemones. One anemone contains a'harem', consisting of a large female, a smaller reproductive male, smaller non-reproductive males. If the female is removed, the reproductive male will change sex and the largest of the non-reproductive males will mature and become reproductive.
It has been shown that fishing pressure can change when the switch from male to female occurs, since fishermen prefer to catch the larger fish. The populations are changing sex at a smaller size, due to natural selection. Protogyny: Where the organism is born as a female, changes sex to a male. Example: wrasses are a group of reef fish in which protogyny is common. Wrasses have an uncommon life history strategy, termed diandry. In these species, two male morphs exists: a terminal phase male. Initial phase males do not spawn in groups with other females, they are not territorial. They are female mimics. Terminal phase males have a distinctively bright coloration. Individuals are born as males or females, but if they are born males, they are not born as terminal phase males. Females and initial phase males can become terminal phase males; the most dominant female or initial phase male replaces any terminal phase male when those males die or abandon the group. Bidirectional Sex Changers: where an organism has female and male reproductive organs, but act as either female or male during different stages in life.
Example: Lythrypnus dalli are a group of coral reef fish in which bidirectional sex change occurs. Once a social hierarchy is established a fish changes sex according to its social status, regardless of the initial sex, based on a simple principle: if the fish expresses subordinate behavior it changes its sex to female, if the fish expresses dominant or not subordinate behavior the fish changes its sex to male. Dichogamy can have both conservation-related implications for humans, as mentioned above, as well as economic implications. For instance, groupers are favoured fish for eating in many Asian countries and are aquacultured. Since the adults take several
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
