Amphibian


Definition:

  • (a.) Of or pertaining to the Amphibia; as, amphibian reptiles.
  • (n.) One of the Amphibia.

Example Sentences:

  • (7) In terms of their chemical structures as well as the potency and efficacy with which they alter acinar cell function, the amphibian peptides plus CCK-OP can be grouped into three pairs: caerulein with CCK-OP, bombesin with litorin, and physalaemin with eledoisin.
  • (8) The same membrane specialization was noted in a previous study of amphibian myoneural junctions, and it was proposed then that the granular elements represent ACh receptor molecules.
  • (9) In relation to the human class I enzyme, the amphibian protein has residue identities exactly halfway (68%) between those for the corresponding avian enzyme (74%) and the human class III enzyme (62%), suggesting an origin of the alcohol dehydrogenase classes very early in or close to the evolution of the vertebrate line.
  • (10) The four hosts (Mollusc -- Crustacean -- Odonat -- Amphibian) are obligatory in the life cycle for it is impossible to infect the Insects directly with the cecariae or the frog (tadpoles as well as adults) with the mesocercariae.

  • (15) Using material on the evolution of the fundus of the oral cavity in amphibians, four principles were established for the origin of heterochronia: efficiency of ontogenesis; adaptability of an earlier (than in ancestors) beginning for functioning of traits; loss of the adaptive significance of a trait at a previous stage, but a preservation of it at a subsequent stage; and, a prolongation of the adaptive significance of a trait at later stages.
