| biological clock | <biology, physiology> An internal biological mechanism which controls certain biological rhythms and biocycles, such as metabolism, sleep cycles, photosynthesis. (21 Mar 1998) |
|---|---|
| biological clocks | The physiological mechanisms that govern the rhythmic occurrence of certain biochemical, physiological, and behavioural phenomena in plants and animals. The pineal gland, which receives input from the optic nerves and connects to the hypothalamus, may be the biological clock in humans. (12 Dec 1998) |
| circadian clock | <physiology> A biological timing mechanism that controls cell synchronisation (a entire population of cells divides simultaneously). (09 Oct 1997) |
|---|---|
| molecular clock | This term has two separate uses. 1. <molecular biology> The rate of fixation of mutations in DNA and thus times the rate of genetic diversification. 2. <cell biology> A biological system capable of maintaining up a timing rhythm or pulse. All such clocks are thought to be entrained by a natural oscillator such as the diurnal rhythm. (18 Nov 1997) |
| ten-o'clock | <botany> A plant, the star-of-Bethlehem. See Star. Source: Websters Dictionary (01 Mar 1998) |
| four-o'clock | 1. <botany> A plant of the genus Mirabilis. There are about half a dozen species, natives of the warmer parts of America. The common four-o'clock is M. Jalapa. Its flowers are white, yellow, and red, and open toward sunset, or earlier in cloudy weather; hence the name. It is also called marvel of Peru, and afternoon lady. 2. <zoology> The friar bird; so called from its cry, which resembles these words. Source: Websters Dictionary (01 Mar 1998) |
| lens clock | A device for measuring the radii of the curvature of a spectacle lens. Synonym: lens clock. Origin: Geneva, Switzerland (05 Mar 2000) |
| biological | Pertaining to biology. (18 Nov 1997) |
| biological agent | <microbiology> A disease-causing microorganism or virus, or other toxic biological matter, which is used as a weapon during war. (21 Mar 1998) |
| biological assay | <technique> Once a pharmaceutical protein is isolated from the cells in which it was grown, researchers perform tests to measure the protein's biological activity. It must maintain a certain minimal level of biological activity to be used for animal or clinical testing or, later, for market. Researchers also test to confirm that the isolated protein is identical to the desired protein. (21 Mar 1998) |
| biological assessment | A specific process required as part of an environmental assessment. An evaluation of potential effects of a proposed project on proposed, endangered, threatened, and sensitive animal and plant species and their habitats. (05 Dec 1998) |
| biological availability | The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action. (12 Dec 1998) |
| biological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
| biological coefficient | Rarely used term denoting the energy expended by the body at rest. (05 Mar 2000) |
| biological containment | <molecular biology> Refers to any number of methods to contain genetically engineered organisms by creating biochemical barriers to prevent them from growing outside the laboratory. In the case of bacteria and yeasts, genes in the organisms may be altered so that they need to have a supply of a nutrient that is normally found only in the laboratory. (21 Mar 1998) |
| biological control | <agriculture> The agricultural use of living things, such as parasites, diseases, and predators, to control or eliminate others, such as weeds and pests, rather than by using chemicals (herbicides and pesticides). (21 Mar 1998) |
| biological dressings | Human or animal tissue used as temporary wound coverings. (12 Dec 1998) |
