(15) Based on the fact that all hibernators, at their regulated minimal body temperature, display a uniform turnover rate, related to body weight, the hypothesis is developed that cold tolerance of mammals is generally limited by a common specific minimal metabolic rate, which larger organisms, because of their lower basal metabolism, already attain in less profound hypothermia.
(16) Based on morphological, virological, biochemical and molecular biological data, it is proposed that the presence of endogenous retrovirus particles in the placental cytotrophoblasts of many mammals is indicative of some beneficial action provided by the virus in relation to cell fusion, syncytiotrophoblast formation and the creation of the placenta.

Ringtail
Definition:
(n.) A bird having a distinct band of color across the tail, as the hen harrier.
(n.) A light sail set abaft and beyong the leech of a boom-and-gaff sail; -- called also ringsail.
Example Sentences:
