Organic chemistry

Organic chemistry

Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives. These compounds may contain any number of other elements, including hydrogen, nitrogen, oxygen, the halogens as well as phosphorus, silicon, and sulfur.[1][2][3]

Organic compounds are structurally diverse. The range of application of organic compounds is enormous. They either form the basis of, or are important constituents of, many products including plastics, drugs, petrochemicals, food, explosives, and paints. They form the basis of almost all earthly life processes (with very few exceptions).

Giant Anteaters, Giant Anteater

Anteaters are edentate animals—they have no teeth. But their long tongues are more than sufficient to lap up the 35,000 ants and termites they swallow whole each day.

The anteater uses its sharp claws to tear an opening into an anthill and put its long snout and efficient tongue to work. But it has to eat quickly, flicking its tongue up to 160 times per minute. Ants fight back with painful stings, so an anteater may spend only a minute feasting on each mound. Anteaters never destroy a nest, preferring to return and feed again in the future.
