11. All cetaceans, including belugas, have physiological adaptations designed to conserve oxygen while they are under water. 12. Lamarckism has made a comeback, however, among evolutionary biologists who study behavioral rather than physiological adaptations . 13. Plants with such morphological and physiological adaptations are. 14. :: : : : A normal physiological adaptation taken to its extreme is not a normal physiological adaptation. 15. :: : : : A normal physiological adaptation taken to its extreme is not a normal physiological adaptation . 16. Hummingbirds and sunbirds also have special anatomical and physiological adaptations that allow them to quickly excrete excess water. 17. Mangrove plants require a number of physiological adaptations to overcome the problems of mangrove tree species show distinct zonation. 18. After several weeks of hypoventilation training, physiological adaptations occur that delay the onset of acidosis during a maximal exertion test. 19. Like most other birds, basic physiological adaptations control both heat loss in warm conditions and heat retention in cooler conditions. 20. This physiological adaptation isn't always pleasant and, above about 18, 000 feet, it isn't something that can be sustained indefinitely.
