| adaptive behaviour scales | A behavioural assessment device to quantify the levels of skills of mentally retarded and developmentally delayed individuals in interacting with the environment; consists of three developmentally related factors: 1) personal self-sufficiency, e.g., eating, dressing; 2) community self-sufficiency, e.g., shopping, communicating; 3) personal and social responsibility, e.g., use of leisure time, job performance.

| adaptive enzyme | Inducible enzyme, an enzyme that can be detected in a growing culture of a microorganism, after the addition of a particular substance (inducer) to the culture medium, but was not detectable prior to the addition and can act on the inducer. A prototype is the beta-galactosidase of Escherichia coli, synthesised upon the addition of various galactosides, whether or not these are good substrates. Compare: constitutive enzyme. Synonym: adaptive enzyme. (05 Mar 2000) |
