Chemical element
–
A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei. There are 118 elements that have identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, iron is the most abundant element making up Earth, while oxygen is the most common element in the Earths crust. Chemical elements constitute all of the matter of the universe. The two lightest elements, hydrogen and helium, were formed in the Big Bang and are the most common elements in the universe. The next three elements were formed mostly by cosmic ray spallation, and are rarer than those that follow. Formation of elements with from 6 to 26 protons occurred and continues to occur in main sequence stars via stellar nucleosynthesis, the high abundance of oxygen, silicon, and iron on Earth reflects their common production in such stars. The term element is used for atoms with a number of protons as well as for a pure chemical substance consisting of a single element. A single element can form multiple substances differing in their structure, when different elements are chemically combined, with the atoms held together by chemical bonds, they form chemical compounds. Only a minority of elements are found uncombined as relatively pure minerals, among the more common of such native elements are copper, silver, gold, carbon, and sulfur. All but a few of the most inert elements, such as gases and noble metals, are usually found on Earth in chemically combined form. While about 32 of the elements occur on Earth in native uncombined forms. For example, atmospheric air is primarily a mixture of nitrogen, oxygen, and argon, the history of the discovery and use of the elements began with primitive human societies that found native elements like carbon, sulfur, copper and gold. Later civilizations extracted elemental copper, tin, lead and iron from their ores by smelting, using charcoal, alchemists and chemists subsequently identified many more, almost all of the naturally occurring elements were known by 1900. Save for unstable radioactive elements with short half-lives, all of the elements are available industrially, almost all other elements found in nature were made by various natural methods of nucleosynthesis. On Earth, small amounts of new atoms are produced in nucleogenic reactions, or in cosmogenic processes. Of the 94 naturally occurring elements, those with atomic numbers 1 through 82 each have at least one stable isotope, Isotopes considered stable are those for which no radioactive decay has yet been observed. Elements with atomic numbers 83 through 94 are unstable to the point that radioactive decay of all isotopes can be detected, the very heaviest elements undergo radioactive decay with half-lives so short that they are not found in nature and must be synthesized

Citrus
–
Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops like oranges, lemons, grapefruit, pomelo, the most recent research indicates an origin in Australia, New Caledonia and New Guinea. Citrus fruit has been cultivated in an area since ancient times. At various times, citrus plants were thought to be native to Asia, Europe, but the European oranges were originally brought from India at around the time of Alexander the Great, and the native oranges of Florida actually originated with the Spanish Conquistadors. The lemon reached Europe during the time of classical Rome, the generic name originated from Latin, where it referred to either the plant now known as Citron or a conifer tree. It is somehow related to the ancient Greek word for cedar and this may be due to perceived similarities in the smell of citrus leaves and fruit with that of cedar. Collectively, Citrus fruits and plants are known by the Romance loanword agrumes. The large citrus fruit of today evolved originally from small, edible berries over millions of years, Citrus plants diverged from a common ancestor about 15 million years ago, which was about when it diverged from the closely related severinia, for example the Chinese box orange. These estimates are made using genetic mapping of plant chloroplasts, the three original species in the citrus genus that have been hybridized into most modern commercial citrus fruit are the mandarin orange, pummelo, and citron. Within the last few years, all common citrus fruits were created by crossing those original species. Something similar has occurred with the array of chili peppers originating in the hybridization of a few initial species. Natural and cultivated citrus hybrids include commercially important fruit such as oranges, grapefruit, lemons, limes, apart from these four core citrus species, there are Australian limes and the recently discovered Mangshanyegan. Kumquats and Clymenia sp. are now considered to belong within the citrus genus. Trifoliate orange, which is used as commercial rootstock, is an outgroup. Phylogenetic analysis suggests the species of Oxanthera from New Caledonia should be transferred to the genus Citrus and these plants are large shrubs or small to moderate-sized trees, reaching 5–15 m tall, with spiny shoots and alternately arranged evergreen leaves with an entire margin. The flowers are solitary or in corymbs, each flower 2–4 cm diameter, with five white petals and numerous stamens. The fruit is a hesperidium, a berry, globose to elongated, 4–30 cm long and 4–20 cm diameter. The outermost layer of the pericarp is a called the flavedo

Soft drink
–
A soft drink is a drink that typically contains carbonated water, a sweetener, and a natural or artificial flavoring. The sweetener may be sugar, high-fructose corn syrup, fruit juice, sugar substitutes, Soft drinks may also contain caffeine, colorings, preservatives, and other ingredients. Soft drinks are called soft in contrast to hard drinks, small amounts of alcohol may be present in a soft drink, but the alcohol content must be less than 0. 5% of the total volume if the drink is to be considered non-alcoholic. Fruit punch, tea, and other such non-alcoholic beverages are technically soft drinks by this definition but are not generally referred to as such, Soft drinks may be served chilled, over ice cubes or at room temperature. In rare cases, some drinks, such as Dr Pepper. Soft drinks are available in formats, including cans, glass bottles. Soft drinks are widely available at fast food restaurants, movie theaters, convenience stores, casual dining restaurants, dedicated soda stores. Soda fountain drinks are served in paper or plastic disposable cups in the first three venues. In casual dining restaurants and bars, soft drinks are served in glasses. Soft drinks may be drunk with straws or sipped directly from the cups, Soft drinks are mixed with other ingredients in several contexts. In Western countries, in bars and other places where alcohol is served many mixed drinks are made by blending a soft drink with hard liquor, one well-known example is the rum and coke, which may also contain lime juice. Some homemade fruit punch recipes, which may or may not contain alcohol, contain a mixture of fruit juices. At ice cream parlours and 1950s-themed diners, ice cream floats are often sold, two popular ice cream floats are the coke float and the root beer float, which consist of a scoop of ice cream placed in a tall glass of the respectively named soft drinks. Due to the sugar content in typical soft drinks, they may also be called sugary drinks. In Spanish, they use the English equivalent of refreshment, or also commonly called gaseosa. In the United States, the 2003 Harvard Dialect Survey tracked the usage of the nine most common names, over half of the survey respondents preferred the term soda, which was dominant in the Northeastern United States, California, and the areas surrounding Milwaukee and St. Louis. The term tonic is hyperlocal to eastern Massachusetts, although usage is declining, in the English-speaking parts of Canada, the term pop is prevalent, but soft drink is the most common English term used in Montreal. In the United Kingdom and Ireland, the terms fizzy drink, pop and fizzy pop are used in northern England, while mineral is used in Ireland

Food and Drug Administration
–
The Food and Drug Administration is a federal agency of the United States Department of Health and Human Services, one of the United States federal executive departments. As of 2017, 3/4th of the FDA budget is funded by the pharmaceutical companies due to the Prescription drug user fee act and these include regulating lasers, cellular phones, condoms and control of disease on products ranging from certain household pets to sperm donation for assisted reproduction. The FDA is led by the Commissioner of Food and Drugs, appointed by the President with the advice, the Commissioner reports to the Secretary of Health and Human Services. Dr. Robert M. Califf, MD is the current commissioner, who took over in February 2016 for Dr. Stephen Ostroff, the FDA has its headquarters in unincorporated White Oak, Maryland. The agency also has 223 field offices and 13 laboratories located throughout the 50 states, the United States Virgin Islands, in 2008, the FDA began to post employees to foreign countries, including China, India, Costa Rica, Chile, Belgium, and the United Kingdom. The site was renamed from the White Oak Naval Surface Warfare Center to the Federal Research Center at White Oak, the first building, the Life Sciences Laboratory, was dedicated and opened with 104 employees on the campus in December 2003. Only one original building from the facility was kept. All other buildings are new construction, the project is slated to be completed by 2017, assuming future Congressional funding While most of the Centers are located in the Washington, D. C. The Office of Regulatory Affairs is considered the eyes and ears of the agency, the Office of Regulatory Affairs is divided into five regions, which are further divided into 20 districts. Districts are based roughly on the divisions of the federal court system. Each district comprises a main office and a number of Resident Posts. ORA also includes the Agencys network of laboratories, which analyze any physical samples taken. Though samples are usually food-related, some laboratories are equipped to analyze drugs, cosmetics, the Office of Criminal Investigations was established in 1991 to investigate criminal cases. Unlike ORA Investigators, OCI Special Agents are armed, and dont focus on aspects of the regulated industries. In many cases, OCI pursues cases involving Title 18 violations, OCI Special Agents often come from other criminal investigations backgrounds, and work closely with the Federal Bureau of Investigation, Assistant Attorney General, and even Interpol. OCI receives cases from a variety of sources—including ORA, local agencies, OCI is a smaller branch, comprising about 200 agents nationwide. The FDA frequently works with federal agencies, including the Department of Agriculture, Drug Enforcement Administration, Customs and Border Protection. Often local and state government agencies also work with the FDA to provide regulatory inspections, the FDA regulates more than US$1 trillion worth of consumer goods, about 25% of consumer expenditures in the United States

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located 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, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Mountain Dew
–
Mountain Dew is a carbonated soft drink brand produced and owned by PepsiCo. The original formula was invented in 1940 by Tennessee beverage bottlers Barney, a revised formula was created by Bill Bridgforth in 1958. The rights to this formula were obtained by the Tip Corporation of Marion, William H. Bill Jones of the Tip corporation further refined the formula, launching that version of Mountain Dew in 1961. Between the 1940s and 1980s, there was just one variety of Mountain Dew, Diet Mountain Dew was introduced in 1988, followed by Mountain Dew Red, which was introduced and subsequently discontinued in 1988. In 2001, a flavor called Code Red debuted. This product line extension trend has continued, with expansion into specialty, limited production, region-specific. Production was first extended to the UK in 1996, but was phased out in 1998, a similarly named but very different-tasting product has been sold in the UK under the name Mountain Dew Energy since 2010 and in Ireland since Spring 2011. The product was renamed in 2014 to simply just Mountain Dew, as of 2009, Mountain Dew represented a 6.7 percent share of the overall carbonated soft drinks market in the U. S. Its competition includes The Coca-Cola Companys Mello Yello and Surge, and Dr Pepper Snapple Groups Sun Drop, Tennessee bottlers Barney and Ally Hartman developed Mountain Dew as a mixer in the 1940s. Soft drinks were regional in the 1930s, and the Hartmans had difficulty in Knoxville obtaining their preferred soda to mix with liquor, preferably whiskey, originally a nineteenth-century generic term for whiskey, especially Highland Scotch whiskey, the name was trademarked for the soft drink in 1948. Charles Gordon, who had partnered with William Swartz to bottle and promote Dr. Enuf, was introduced to Mountain Dew when he met the Hartman brothers on a train and they offered him a sample. Gordon and the Hartman brothers subsequently made a deal to bottle Mountain Dew by the Tri-Cities Beverage Corporation in Johnson City, the Hartman brothers also asked Coca-Cola for input on their soda, the Coca-Cola Company refused their offer. The Tip Corporation of Marion, Virginia bought the rights to Mountain Dew, revising the flavor, in 1964, Pepsico purchased the Tip Corporation and thus acquired the rights to Mountain Dew. In 1999, the Virginia legislature recognized Bill Jones and the Town of Marion for their role in the history of Mountain Dew, Mountain Dew was originally Southern and/or Scots/Irish slang for moonshine. Using it as the name for the soda was originally suggested by Carl E. Retzke at an Owens-Illinois Inc. meeting in Toledo, Ohio, early bottles and signage carried the reference forward by showing a cartoon-stylized hillbilly. PepsiCo acquired the Mountain Dew brand in 1964, and shortly thereafter in 1969 the logo was modified as the sought to shift its focus to a younger. This direction continued as the logo remained the same through the 1970s, 1980s, later updates to the logo were made in 1998 and then again in 2005. In October 2008, the Mountain Dew logo was redesigned to Mtn Dew within the U. S. market, the returning flavors Pitch Black, Supernova, Typhoon, and Game Fuel were given redesigned packaging and logos for their 2011 re-release
