Arkansas () is a state in the South Central region of the United States, home to more than three million people as of 2018. Its name is from the Osage language, a Dhegiha Siouan language, and referred to their relatives, the Quapaw people. The state's diverse geography ranges from the mountainous regions of the Ozark and Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta.
Arkansas is the 29th largest by area and the 33rd most populous U.S. state. The capital and most populous city is Little Rock, in the central part of the state, a hub for transportation, business, culture, and government. The northwestern corner of the state, including the Fayetteville–Springdale–Rogers Metropolitan Area and Fort Smith metropolitan area, is a population, education, and economic center. The largest city in the state's eastern part is Jonesboro. The largest city in the state's southeastern part is Pine Bluff.
Previously part of French Louisiana and the Louisiana Purchase, the Territory of Arkansas was admitted to the Union as the 25th state on June 15, 1836. Much of the Delta had been developed for cotton plantations, and landowners there largely depended on enslaved African Americans' labor.

ZZ Top is an American rock band formed in 1969 in Houston, Texas. The group consists of founder Billy Gibbons (vocals, guitar), Dusty Hill (vocals, bass), and Frank Beard (drums). Initially rooted in blues, the band's style has evolved throughout their career, with a signature sound based on Gibbons' blues guitar style and the rhythm section of Hill and Beard. Their lyrics, often embellished with sexual innuendo, focus on their Texas roots and sense of humor. Popular for their live performances and the identical physical appearances of Gibbons and Hill—who are rarely seen without their long beards, sunglasses, and Stetson hats—the group has staged several elaborate tours.
ZZ Top formed after the demise of Moving Sidewalks, Gibbons' previous band. Within a year, they signed with London Records and released ZZ Top's First Album (1971). Subsequent releases, such as their first top-ten album Tres Hombres (1973) and the singles "La Grange" and "Tush", gained extensive radio airplay. By the mid-1970s, they had become renowned in North America for their live act, highlighted by their performances during the Worldwide Texas Tour from 1976 to 1977, which was a critical and commercial success.Following a two-year break in response to creative stagnation and exhaustion, ZZ Top reinvented themselves in the late 1970s with a new musical direction and their now-famous public image. Beginning with their albums Degüello (1979) and El Loco (1981), they experimented with instruments including clavinets, saxophones, and synthesizers.

Benjamin Franklin  (January 17, 1706 [O.S. January 6, 1705] –  April 17, 1790) was one of the Founding Fathers of the United States. A polymath, he was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania.Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing the Pennsylvania Gazette at the age of 23. He became wealthy publishing this and Poor Richard's Almanack, which he authored under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of the policies of the British Parliament and the Crown.He pioneered and was the first president of Academy and College of Philadelphia which opened in 1751 and later became the University of Pennsylvania.

Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southern Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona, and Ndebele the most common.
Since the 11th century, present-day Zimbabwe has been the site of several organised states and kingdoms such as the Rozvi and Mthwakazi kingdoms, as well as being a major route for migration and trade. The British South Africa Company of Cecil Rhodes first demarcated the present territory during 1890 when they conquered Mashonaland and later in 1893 Matabeleland after a fierce resistance by Matabele people known as the First Matabele War. Company rule ended in 1923 with the establishment of Southern Rhodesia as a self-governing British colony. In 1965, the conservative white minority government unilaterally declared independence as Rhodesia. The state endured international isolation and a 15-year guerrilla war with black nationalist forces; this culminated in a peace agreement that established universal enfranchisement and de jure sovereignty as Zimbabwe in April 1980. Zimbabwe then joined the Commonwealth of Nations, from which it was suspended in 2002 for breaches of international law by its then-government under Robert Mugabe, and from which it withdrew in December 2003.

Gävle (pronounced [ˈjɛ̌ːvlɛ] (listen)) is a city in Sweden, the seat of Gävle Municipality and the capital of Gävleborg County. It had 102 418 inhabitants in 2019, which makes it the 13th most populated city in Sweden. It is the oldest city in the historical Norrland (Sweden's Northern Lands), having received its charter in 1446 from Christopher of Bavaria. However, Gävle is far nearer to the greater Stockholm region than it is to the other major settlements in Norrland and has a much milder climate than associated with said region.
In recent years, the city has received much international attention due to its large Yule Goat figure made of straw - the Gävle Goat. The goat is erected in December each year and is often subsequently vandalized, usually by being set on fire. The goat has now become a symbol for the city and is being used for various marketing purposes.


== History ==

It is believed that the name Gävle derives from the word gavel, meaning river banks in Old Swedish and referring to the Gavleån (Gävle River). The oldest settlement was called Gävle-ägarna, which means "Gavel-owners". This name was shortened to Gävle, then Gefle, and finally Gävle.

The Statue of Liberty (Liberty Enlightening the World; French: La Liberté éclairant le monde) is a colossal neoclassical sculpture on Liberty Island in New York Harbor within New York City, in the United States. The copper statue, a gift from the people of France to the people of the United States, was designed by French sculptor Frédéric Auguste Bartholdi and its metal framework was built by Gustave Eiffel. The statue was dedicated on October 28, 1886.
The statue is a figure of Libertas, a robed Roman liberty goddess. She holds a torch above her head with her right hand, and in her left hand carries a tabula ansata inscribed JULY IV MDCCLXXVI (July 4, 1776 in Roman numerals), the date of the U.S. Declaration of Independence. A broken shackle and chain lie at her feet as she walks forward, commemorating the recent national abolition of slavery. After its dedication, the statue became an icon of freedom and of the United States, seen as a symbol of welcome to immigrants arriving by sea.
Bartholdi was inspired by a French law professor and politician, Édouard René de Laboulaye, who is said to have commented in 1865 that any monument raised to U.S. independence would properly be a joint project of the French and U.S. peoples. The Franco-Prussian War delayed progress until 1875, when Laboulaye proposed that the French finance the statue and the U.S. provide the site and build the pedestal. Bartholdi completed the head and the torch-bearing arm before the statue was fully designed, and these pieces were exhibited for publicity at international expositions.

Scotland (Scots: Scotland, Scottish Gaelic: Alba [ˈal̪ˠapə] (listen)) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a 96-mile (154 km) border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and the Irish Sea to the south. The country also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt – the plain between the Scottish Highlands and the Southern Uplands – in the Scottish Lowlands.
Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scottish Government to each subdivision. Scotland is the second largest country in the United Kingdom, and accounted for 8.3% of the population in 2012.The Kingdom of Scotland emerged as an independent sovereign state in the Early Middle Ages and continued to exist until 1707. By inheritance in 1603, James VI of Scotland became king of England and Ireland, thus forming a personal union of the three kingdoms. Scotland subsequently entered into a political union with the Kingdom of England on 1 May 1707 to create the new Kingdom of Great Britain.

The koala or, inaccurately, koala bear  (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats, which are members of the family Vombatidae. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
Koalas typically inhabit open eucalypt woodlands, and the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to 20 hours a day.

Salar de Uyuni (or Salar de Tunupa) is the world's largest salt flat, or playa, at over 10,000 square kilometres (3,900 sq mi) in area. It is in the Daniel Campos Province in Potosí in southwest Bolivia, near the crest of the Andes at an elevation of 3,656 meters (11,995 ft) above sea level.The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average elevation variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. The large area, clear skies, and exceptional flatness of the surface make the Salar ideal for calibrating the altimeters of Earth observation satellites. Following rain, a thin layer of dead calm water transforms the flat into the world's largest mirror, 129 kilometers (80 miles) across.The Salar serves as the major transport route across the Bolivian Altiplano and is a prime breeding ground for several species of flamingos. Salar de Uyuni is also a climatological transitional zone since the towering tropical cumulus congestus and cumulonimbus incus clouds that form in the eastern part of the salt flat during the summer cannot permeate beyond its drier western edges, near the Chilean border and the Atacama Desert.Salar has been used as a filming location for movies such as Star Wars: The Last Jedi (2017; as planet Crait), The Fall (2006), Salt and Fire (2016), The Unseen (2017), and several others. 


== Formation, geology, and climate ==
Salar de Uyuni is part of the Altiplano of Bolivia in South America. The Altiplano is a high plateau, which was formed during uplift of the Andes mountains. The plateau includes fresh and saltwater lakes as well as salt flats and is surrounded by mountains with no drainage outlets.

The wood frog (Lithobates sylvaticus or Rana sylvatica) has a broad distribution over North America, extending from the boreal forest of the north to the southern Appalachians, with several notable disjunct populations including lowland eastern North Carolina. The wood frog has garnered attention by biologists over the last century because of its freeze tolerance, relatively great degree of terrestrialism (for a ranid), interesting habitat associations (peat bogs, vernal pools, uplands), and relatively long-range movements.
The ecology and conservation of the wood frog has attracted research attention in recent years because they are often considered "obligate" breeders in ephemeral wetlands (sometimes called "vernal pools") that are themselves more imperiled than the species that breed in them. The wood frog has been proposed to be the official state amphibian of New York.


== Description ==

Wood frogs range from 51 to 70 mm (2.0 to 2.8 in) in length and size Females are larger than males. Adult wood frogs are usually brown, tan, or rust-colored, and usually have a dark eye mask. Individual frogs are capable of varying their color; Conant (1958) depicts one individual when light brown and dark brown at different times. The underparts of wood frogs are pale with a yellow or green cast.

A small brown frog with a dark eye mask in the woods is likely to be a wood frog. No other species has a similar appearance to the wood frog in North America.

The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whale suborder Mysticeti. Reaching a maximum confirmed length of 29.9 metres (98 ft) and a weighing up to 199 tonnes (196 long tons; 219 short tons), it is the largest animal known to have existed. The blue whale's long and slender body can be various shades of grayish-blue dorsally and somewhat lighter underneath.
The Society for Marine Mammalogy's Committee on Taxonomy currently recognizes four subspecies: B. m. musculus in the North Atlantic and North Pacific, B. m. intermedia in the Southern Ocean, B. m. brevicauda (the pygmy blue whale) in the Indian Ocean and South Pacific Ocean, B. m. indica in the Northern Indian Ocean. There is also a population in the waters off Chile that may constitute a fifth subspecies. 
Blue whales are filter feeders and their diet consists almost exclusively of euphausiids (krill).

In biology, a population is a number of all the organisms of the same group or species who live in a particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas.In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of populations. 
Population, in simpler terms, is the number of people in a city or town, region, country or world; population is usually determined by a process called census (a process of collecting, analyzing, compiling and publishing data).


== Population genetics (ecology) ==
In population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring, and such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same species.
If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele (gamete) frequencies can be converted to genotype (zygote) frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics.This seldom occurs in nature: localization of gamete exchange – through dispersal limitations, preferential mating, cataclysm, or other cause – may lead to small actual gamodemes which exchange gametes reasonably uniformly within themselves but are virtually separated from their neighboring gamodemes. However, there may be low frequencies of exchange with these neighbors.
