The horse (Equus ferus caballus) is one of two extant subspecies of Equus ferus, or the wild horse. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed animal of today. Humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. Horses in the subspeciescaballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated, such as the endangered Przewalski’s Horse, a separate subspecies, and the only remaining true wild horse. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size,colors, markings, breeds, locomotion, and behavior.

The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, carnivorous mammal. It is often called the housecatwhen kept as an indoor pet, or simply the cat when there is no need to distinguish it from other felids and felines. Cats are valued by humans for companionship and ability to hunt vermin and household pests. They are primarily nocturnal.

The domestic dog (Canis lupus familiaris), is a subspecies of the gray wolf (Canis lupus), a member of the Canidae family of the mammilian order Carnivora. The term “domestic dog” is generally used for both domesticated and feral varieties. The dog may have been the first animal to be domesticated, and has been the most widely kept working, hunting, and companion animal in human history. The word “dog” may also mean the male of a canine species, as opposed to the word “bitch” for the female of the species.

A boat is a watercraft of any size designed to float or plane, to provide passage across water. Usually this water will be inland (lakes) or in protected coastal areas. However, boats such as the whaleboat were designed to be operated from a ship in an offshore environment. In naval terms, a boat is a vessel small enough to be carried aboard another vessel (a ship). Another less restrictive definition is a vessel that can be lifted out of the water. Strictly speaking and uniquely a submarine is a boat as defined by the Royal Navy. Some boats too large for the naval definition include theGreat Lakes freighter, riverboat, narrowboat and ferryboat. The term armed boat, used primarily by English speaking naval forces, referred to any boat carrying either a cannon or armed occupants, such as marines.

Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. When used without qualification, “weather” is understood to be the weather of Earth.

Weather is driven by density (temperature and moisture) differences between one place and another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow. Because the Earth’s axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. On Earth’s surface, temperatures usually range ±40 °C (100 °F to −40 °F) annually. Over thousands of years, changes in Earth’s orbit affect the amount and distribution of solar energy received by the Earth and influence long-term climate and global climate change.

The study of mountains is calledOrography. Exogeology deals with planetary mountains, which in that branch of science are usually called montes (singular—mons). The highest mountain on Earth based from sea level is Mount Everest (8,848 m (29,029 ft)) in the Himalayas of Asia. The highest known mountain in the Solar System is Olympus Mons on the planet Mars at 21,171 m (69,459 ft). Mountains and mountain ranges on Earth are typically formed by the movement and/or interaction of lithospheric plates.

A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed, the material used to make it and the funds available to build it.

Insects (from Latin insectum, a calque of Greek ἔντομον [éntomon], “cut into sections”) are a class of living creatures within the arthropods that have achitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are among the most diverse groups of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing metazoanlife forms on Earth. Insects may be found in nearly all environments, although only a small number of species occur in the oceans, a habitat dominated by another arthropod group, the crustaceans.

Ana Lúcia Hickmann (born March 1, 1981) is a Brazilian model who has worked for Victoria’s Secret, Nivea, L’Oreal, Clairol, and Bloomingdales. She has appeared in the South African version of the Sports Illustrated Swimsuit Issue, and on the covers of Brazilian Vogue, Marie Claire, and Elle.

She currently distributes her own clothing and cosmetics lines, manages a photography studio and a DJ agency, and also hosts the daytime program Tudo e Possivel, aired by Brazilian TV network Rede Record.^{[citation needed]} One of the regular guests on her show is magician Mario Kamia, who performs a range of tricks and illusions. Some of Kamia’s illusions involve using Hickmann as his assistant, including dividing her into three in the Zig-Zag Girl and sawing her in half using a Buzz Saw.

Hickmann, who is of German heritage, was once listed in the Guinness Book of World Records as “The model with the longest legs”, measuring 46.5″ (118 cm, measured from hip to heel) out of a total height of 73″. Since 2002, the Guinness Book no longer lists this title.^{[citation needed]}

She was ranked #47 and #85 on the Maxim Hot 100 Women of 2004, and 2005, respectively.

On February 14, 1998 she married former model Alexander Corrêa.
