Ammonia-carbon acids that when strung together in long double-bonded chains (peptides) build proteins. The genetic code inscribed in DNA employs twenty of them.
Industry:Biology
Primarily marine organisms, single-celled or multicellular, that use chlorophyll to feed, like plants, but lack the roots, leaves, flowers, etc. Of true plants.
Industry:Biology
Environments contain numerous points of relative stability that enable more than one species to flourish as a climax community. Contrast with Monoclimax Theory.
Industry:Biology
A thin deposit of sediment found on a lake bottom. Because its thickness fluctuates annually, its layers disclose information about the lake's geological past.
Industry:Biology
A plant or animal that has an important effect on the biotic balance in a community. Sometimes used to mean a species that moves into an ecosystem from outside.
Industry:Biology
Ecological succession is driven by pioneer species (often annuals) preparing the way for later (often perennial) species on and into the climax. See Succession.
Industry:Biology
An energy-conserving lowering of metabolism, respiration, heart rate, and body temperature while the body survives on accumulated fat supplies. See Estivation.
Industry:Biology
Those ready for slaughter. Industrially warehoused beef cattle weigh about 1,100 pounds after the steady diet of protein and steroids they are forced to eat.
Industry:Biology
Organisms living on the sea floor. Littoral benthos occupy the space from the high-water spring tide mark to 200 meters down. Deep sea benthos live below that.
Industry:Biology
Long proteins stretched into a triple helix to make strong structural fibers. They are found in hair, tendons, and about a fourth of the human body's protein.
