One of the paired, flexible, and jointed sensory appendages on the head of a crustacean, an insect, or a myriapod (e.g., a centipede).
Industry:Natural environment
A catastrophic, widespread perturbation where major groups of species become extinct in a relatively short time.
Industry:Natural environment
The part of the digestive system of many animals immediately behind the mouth and in front of the esophagus; the throat.
Industry:Natural environment
A longitudinal pressure wave produced by the vibration of molecules in an elastic medium, which can be a liquid, solid, or gas. As the molecules are set in motion, they radiate outwards, colliding into other molecules (compression), then move apart farther than their equilibrium distance (rarefaction), travelling in this manner until they stimulate a sound receptor organ, such as an ear or tactile organ.The receptor translates the mechanical energy of the pressure wave to electrochemical energy of a nervous system, which stimulates a hearing or tactile sensation in the receiving organism; a body of water that is usually broad, elongate, and parallel to the shore between the mainland and one or more islands, e.g., Long Island Sound .
Industry:Natural environment
A positively or negatively charged atom produced through loss or gain of one or more electrons.
Industry:Natural environment
A species which make up a large proportion of a community in terms of its biomass or numbers of individuals.
Industry:Natural environment
The sum total of genes, with all their variations, possessed by a particular species at a particular time.
Industry:Natural environment
The structure enveloping a cell, enclosing the cytoplasm and forming a selective permeability barrier which permits the passage of solvents and solutes into and out of cells. It consists of lipids, proteins and some carbohydrates.
Industry:Natural environment
Energy that travels through space in the form of waves. The highest frequencies in the spectrum of electromagnetic radiation are gamma-rays; the lowest frequencies are radio waves. All electromagnetic radiation travels at the speed of light. Shorter wavelength radiation (eg, ultraviolet) carries more energy and is likely to be more harmful to living tissue.
