(i) | Success of mammals on earth is mainly due to their ability to maintain a constant body temperature |
(ii) | Migration is restricted to animals only. In plants, even the propagules (spores and seeds) cannot migrate |
(iii) | Diapause is a stage of suspended development in many zooplanktons |
(iv) | Most of the animals can maintain internal homeostasis |
(v) | In conformers, the body temperature changes with the ambient temperature but the osmotic concentration of the body fluids does not change with that of ambient water osmotic concentration |
