An alternate care site ( ACS) is a medical treatment facility established in a non-traditional setting during a public-health crisis (or other event causing strain on local medical resources) as a means of providing additional capacity to deliver medical care within a given area. [1] [2] : 1 The term encompasses both civilian-operated medical ...
Allosteric regulation. In biochemistry, allosteric regulation (or allosteric control) is the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site . The site to which the effector binds is termed the allosteric site or regulatory site. Allosteric sites allow effectors to bind to the protein, often ...
Alternative biochemistry. Silicon-based life. Like carbon, silicon can create molecules that are sufficiently large to carry biological information; however, the scope of possible silicon chemistry is far more limited than that of carbon. Silicon dioxide biochemistry. Non-water solvents. Silicon dioxide -based life.
Alternative medicine is any practice that aims to achieve the healing effects of medicine despite lacking biological plausibility, testability, repeatability or evidence of effectiveness. Unlike modern medicine, which employs the scientific method to test plausible therapies by way of responsible and ethical clinical trials, producing ...
Alternative stable state. In ecology, the theory of alternative stable states (sometimes termed alternate stable states or alternative stable equilibria) predicts that ecosystems can exist under multiple "states" (sets of unique biotic and abiotic conditions). These alternative states are non-transitory and therefore considered stable over ...
Evolutionary biology. In biology, polymorphism [1] is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).
Alternation of generations (also known as metagenesis or heterogenesis) [1] is the predominant type of life cycle in plants and algae. In plants both phases are multicellular: the haploid sexual phase – the gametophyte – alternates with a diploid asexual phase – the sporophyte . A mature sporophyte produces haploid spores by meiosis, a ...
Biomedical sciences. A biochemist engaged in bench research. Biomedical sciences are a set of sciences applying portions of natural science or formal science, or both, to develop knowledge, interventions, or technology that are of use in healthcare or public health. [1] Such disciplines as medical microbiology, clinical virology, clinical ...
