Cutaneous Respiration Lab essays

Cutaneous Respiration Lab essays The regulation of salt (NaCl) t isotonic with blood plasma presents a water balance problem, and any environmental fluid not possessing the exact same mixture The importance of the ability of amphibians to osmoregulate in air cannot be minimized because they were the first vertebrate group to exploit the terrestrial environment. More recent vertebrate evolutionary lineages, the reptiles, birds and mammals, have developed adaptations such as more impervious integuments, more efficient kidneys, and the amniotic egg which have freed them more Toads may be expected to have anatomical or physiological mechanisms that allow them to conserve water more efficiently than frogs during short-term exposure to air. Alternatively, the toads exploitation of land more due to behavioral adaptations such as burrowing or nocturnal abilities. In this experiment, we have compared the amount of water loss experienced by an aquatic frog species, and a terrestrially adaptive toad species through their skins. The experimental procedure exposes individuals to the two types of amphibians to dry...
