Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity and inhibition of nearly all voluntary muscles during rapid eye movement (REM) sleep, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but more reactive than a coma or disorders of consciousness, with sleep displaying different, active brain patterns.
Sleep occurs in repeating periods, in which the body alternates between two distinct modes: REM sleep and non-REM sleep. Although REM stands for "rapid eye movement", this mode of sleep has many other aspects, including virtual paralysis of the body. A well-known feature of sleep is the dream, an experience typically recounted in narrative form, which resembles waking life while in progress, but which usually can later be distinguished as fantasy. During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems; these are vital processes that maintain mood, memory, and cognitive function, and play a large role in the function of the endocrine and immune systems. The internal circadian clock promotes sleep daily at night. The diverse purposes and mechanisms of sleep are the subject of substantial ongoing research. Sleep is a highly conserved behavior across animal evolution.Humans may suffer from various sleep disorders, including dyssomnias such as insomnia, hypersomnia, narcolepsy, and sleep apnea; parasomnias such as sleepwalking and rapid eye movement sleep behavior disorder; bruxism; and circadian rhythm sleep disorders. The use of artificial light has substantially altered humanity's sleep patterns.

Facebook (stylized as facebook) is an American online social media and social networking service owned by Facebook, Inc.
Founded in 2004 by Mark Zuckerberg with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, its name comes from the face book directories often given to American university students. Membership was initially limited to Harvard students, gradually expanding to other North American universities and, since 2006, anyone over 13 years old. As of 2020, Facebook claimed 2.8 billion monthly active users, and ranked seventh in global internet usage. It was the most downloaded mobile app of the 2010s.Facebook can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a profile revealing information about themselves. They can post text, photos and multimedia which are shared with any other users who have agreed to be their "friend" or, with different privacy settings, publicly. Users can also communicate directly with each other with Facebook Messenger, join common-interest groups, and receive notifications on the activities of their Facebook friends and pages they follow.
The subject of numerous controversies, Facebook has often been criticized over issues such as user privacy (as with the Cambridge Analytica data scandal), political manipulation (as with the 2016 U.S. elections), mass surveillance, psychological effects such as addiction and low self-esteem, and content such as fake news, conspiracy theories, copyright infringement, and hate speech. Commentators have accused Facebook of willingly facilitating the spread of such content, as well as exaggerating its number of users to appeal to advertisers.

Amerigo Vespucci (; Italian: [ameˈriːɡo veˈsputtʃi]; 9 March 1451  – 22 February 1512) was an Italian-born merchant, explorer, and navigator from the Republic of Florence, from whose name the term "America" is derived. He became a Castillian citizen in 1505.
Between 1497 and 1504, Vespucci participated in at least two voyages of the Age of Discovery, first on behalf of Spain (1499–1500) and then for Portugal (1501–1502). In 1503 and 1505, two booklets were published under his name, containing colourful descriptions of these explorations and other alleged voyages. Both publications were extremely popular and widely read across much of Europe. Although historians still dispute the authorship and veracity of these accounts, at the time they were instrumental in raising awareness of the new discoveries and enhancing the reputation of Vespucci as an explorer and navigator.
Vespucci claimed to have understood, back in 1501 during his Portuguese expedition, that Brazil was part of a continent new to Europeans, which he called the New World. The claim inspired cartographer Martin Waldseemüller to recognize Vespucci's accomplishments in 1507 by applying the Latinized form "America" for the first time to a map showing the New World. Other cartographers followed suit, and by 1532 the name America was permanently affixed to the newly discovered continents.
It is unknown whether Vespucci was ever aware of these honours.

Smoking is a practice in which a substance is burned and the resulting smoke is breathed in to be tasted and absorbed into the bloodstream.  Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a "cigarette".  Smoking is primarily practised as a route of administration for recreational drug use because the combustion of the dried plant leaves vaporizes and delivers active substances into the lungs where they are rapidly absorbed into the bloodstream and reach bodily tissue.  In the case of cigarette smoking these substances are contained in a mixture of aerosol particles and gases and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas into a form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs.  In some cultures, smoking is also carried out as a part of various rituals, where participants use it to help induce trance-like states that, they believe, can lead them to spiritual enlightenment.
Smoking is one of the most common forms of recreational drug use. Tobacco smoking is the most popular form, being practised by over one billion people globally, of whom the majority are in the developing countries. Less common drugs for smoking include cannabis and opium. Some of the substances are classified as hard narcotics, like heroin, but the use of these is very limited as they are usually not commercially available. Cigarettes are primarily industrially manufactured but also can be hand-rolled from loose tobacco and rolling paper.

Zebras (UK: , US: ) (subgenus Hippotigris) are African equines with distinctive black-and-white striped coats. There are three extant species: the Grévy's zebra (Equus grevyi), plains zebra (E. quagga), and the mountain zebra (E. zebra). Zebras share the genus Equus with horses and asses, the three groups being the only living members of the family Equidae. Zebra stripes come in different patterns, unique to each individual. Several theories have been proposed for the function of these stripes, with most evidence supporting them as a form of protection from biting flies. Zebras inhabit eastern and southern Africa and can be found in a variety of habitats such as savannahs, grasslands, woodlands, shrublands, and mountainous areas.
Zebras are primarily grazers and can subsist on lower-quality vegetation. They are preyed on mainly by lions and typically flee when threatened but also bite and kick. Zebra species differ in social behaviour, with plains and mountain zebra living in stable harems consisting of an adult male or stallion, several adult females or mares, and their young or foals; while Grévy's zebra live alone or in loosely associated herds. In harem-holding species, adult females mate only with their harem stallion, while male Grévy's zebras establish territories which attract females and the species is promiscuous.

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean. The structure links the U.S. city of San Francisco, California—the northern tip of the San Francisco Peninsula—to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. The bridge is one of the most internationally recognized symbols of San Francisco and California. It was initially designed by engineer Joseph Strauss in 1917. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers.The Frommer's travel guide describes the Golden Gate Bridge as "possibly the most beautiful, certainly the most photographed, bridge in the world." At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, with a main span of 4,200 feet (1,280 m) and a total height of 746 feet (227 m).


== History ==


=== Ferry service ===

Before the bridge was built, the only practical short route between San Francisco and what is now Marin County was by boat across a section of San Francisco Bay. A ferry service began as early as 1820, with a regularly scheduled service beginning in the 1840s for the purpose of transporting water to San Francisco.The Sausalito Land and Ferry Company service, launched in 1867, eventually became the Golden Gate Ferry Company, a Southern Pacific Railroad subsidiary, the largest ferry operation in the world by the late 1920s. Once for railroad passengers and customers only, Southern Pacific's automobile ferries became very profitable and important to the regional economy. The ferry crossing between the Hyde Street Pier in San Francisco and Sausalito Ferry Terminal in Marin County took approximately 20 minutes and cost $1.00 per vehicle, a price later reduced to compete with the new bridge. The trip from the San Francisco Ferry Building took 27 minutes.

I, or i, is the ninth letter and the third vowel letter of the modern English alphabet and the ISO basic Latin alphabet. Its name in English is i (pronounced ), plural ies.


== History ==
In the Phoenician alphabet, the letter may have originated in a hieroglyph for an arm that represented a voiced pharyngeal fricative (/ʕ/) in Egyptian, but was reassigned to /j/ (as in English "yes") by Semites, because their word for "arm" began with that sound. This letter could also be used to represent /i/, the close front unrounded vowel, mainly in foreign words.
The Greeks adopted a form of this Phoenician yodh as their letter iota (⟨Ι, ι⟩) to represent /i/, the same as in the Old Italic alphabet. In Latin (as in Modern Greek), it was also used to represent /j/ and this use persists in the languages     that descended from Latin. The modern letter 'j' originated as a variation of 'i', and both were used interchangeably for both the vowel and the consonant, coming to be differentiated only in the 16th century.  The dot over the lowercase 'i' is sometimes called a tittle.  In the Turkish alphabet, dotted and dotless I are considered separate letters, representing a front and back vowel, respectively, and both have uppercase ('I', 'İ') and lowercase ('ı', 'i') forms.


== Use in writing systems ==


=== English ===
In Modern English spelling, ⟨i⟩ represents several different sounds, either the diphthong  ("long" ⟨i⟩) as in kite, the short  as in bill, or the ⟨ee⟩ sound  in the last syllable of machine.

Cap'n Crunch is a corn and oat breakfast cereal manufactured by Quaker Oats Company, a subsidiary of PepsiCo since 2001. After introducing the original cereal in 1963, marketed simply as Cap'n Crunch, Quaker Oats has since introduced numerous flavors and seasonal variations, some for a limited time — and currently offers a Cap'n Crunch product line.
The original Cap'n Crunch cereal was developed to recall a recipe of brown sugar and butter over rice.  It was one of the first cereals to use an oil coating to deliver its flavoring, which required an innovative baking process.


== Product history ==

Pamela Low, a flavorist at Arthur D. Little, developed the original Cap'n Crunch flavor in 1963—recalling a recipe of brown sugar and butter her grandmother Luella Low served over rice
 at her home in Derry, New Hampshire.Low created the flavor coating for Cap'n Crunch, describing it as giving the cereal a quality she called "want-more-ishness". After her death in 2007, The Boston Globe called Low "the mother of Cap'n Crunch." At Arthur D. Little, Low had also worked on the flavors for Heath, Mounds and Almond Joy candy bars.In 1965, the Quaker Oats Company awarded the Fredus N. Peters Award to Robert Rountree Reinhart, Sr. for his leadership in directing the development team of Cap'n Crunch. Reinhart developed a technique in the manufacture of Cap'n Crunch, using oil in its recipe as a flavor delivery mechanism — which initially made the cereal difficult to bake properly.


== Marketing ==
Quaker Oats had a marketing plan for Cap'n Crunch, before it had developed the flavor. The product line is heralded by a cartoon mascot named Cap'n Crunch.

Kermit the Frog is a Muppet character created and originally performed by Jim Henson. Introduced in 1955, Kermit serves as the straight man protagonist of numerous Muppet productions, most notably Sesame Street and The Muppet Show, as well as in other television series, feature films, specials, and public service announcements through the years.
Henson performed Kermit until his death in 1990, and then Steve Whitmire performed Kermit from that time until his dismissal in 2016. Kermit has been performed by Matt Vogel from 2017. He was also voiced by Frank Welker in Muppet Babies and occasionally in other animation projects, and is voiced by Matt Danner in the 2018 reboot of Muppet Babies.
Kermit performed the hit singles "Bein' Green" in 1970 and "Rainbow Connection" in 1979 for The Muppet Movie, the first feature-length film featuring the Muppets. Kermit's original performance of "Rainbow Connection" reached No. 25 on the Billboard Hot 100 and was added to the Library of Congress’s National Recording Registry in 2021.Kermit's iconic look and voice have been recognizable in popular culture worldwide since, and in 2006, the character was credited as the author of Before You Leap: A Frog's Eye View of Life's Greatest Lessons, an "autobiography" told from the perspective of the character himself.


== History and development ==
Kermit the Frog first appeared on May 9, 1955, in the premiere of WRC-TV's Sam and Friends. This prototype Kermit was created from a discarded turquoise spring coat belonging to Jim Henson's mother and two ping pong ball halves for eyes.Initially, Kermit was a vague lizard-like creature.

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans.
Under this broader definition, the earliest known sharks date back to more than 420 million years ago. Acanthodians are often referred to as "spiny sharks"; though they are not part of Chondrichthyes proper, they are a paraphyletic assemblage leading to cartilaginous fish as a whole.  Since then, sharks have diversified into over 500 species. They range in size from the small dwarf lanternshark (Etmopterus perryi), a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark (Rhincodon typus), the largest fish in the world, which reaches approximately 12 metres (40 ft) in length. Sharks are found in all seas and are common to depths of 2,000 metres (6,600 ft). They generally do not live in freshwater although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwater. Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics.

A language is a structured system of communication used by humans, including speech (spoken language), gestures (sign language) and writing. The most widely-spoken languages have a writing system composed of glyphs to inscribe the original sound or gesture and its meaning.The scientific study of language is called linguistics. Critical examinations of languages, such as philosophy of language, the relationships between language and thought, etc, such as how words represent experience, have been debated at least since Gorgias and Plato in ancient Greek civilization. Thinkers such as Rousseau (1712 – 1778) have debated that language originated from emotions, while others like Kant (1724 –1804), have held that languages originated from rational and logical thought. Twentieth century philosophers such as Wittgenstein (1889 – 1951) argued that philosophy is really the study of language itself. Major figures in contemporary linguistics of these times include Ferdinand de Saussure and Noam Chomsky.
Estimates of the number of human languages in the world vary between 5,000 and 7,000. However, any precise estimate depends on the arbitrary distinction (dichotomy) between languages and dialect. Natural languages are spoken or signed, but any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, in writing, whistling, signing, or braille. In other words, human language is modality-independent, but written or signed language is the way to inscribe or encode the natural human speech or gestures.

American football, referred to simply as football in the United States and Canada and also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.
American football evolved in the United States, originating from the sports of soccer and rugby. The first American football match was played on November 6, 1869, between two college teams, Rutgers and Princeton, using rules based on the rules of soccer at the time. A set of rule changes drawn up from 1880 onward by Walter Camp, the "Father of American Football", established the snap, the line of scrimmage, eleven-player teams, and the concept of downs. Later rule changes legalized the forward pass, created the neutral zone and specified the size and shape of the football. The sport is closely related to Canadian football, which evolved in parallel with and at the same time as the American game (although their rules were developed independently from those of Camp).
