Question

Write the comparative account of brain of amphibia and mammal

Answer 1

There are huge differences between mammals and amphibians in many ways based on their characteristics. Mammals have a skin that conserves water and do not need to stay moist, but amphibians must stay wet because they do part of their breathing via the skin, and they cannot effectively hold water within their body. Mammals are warm blooded with four chambered hearts, but amphibians are cold blooded and have three chambered hearts. Amphibians lay eggs in water, (except some species of frog which give birth to live young, rather than laying eggs, such as members of the African genus Nectophrynoides) but most mammals give birth to live young (except a few that lay eggs on land) for example Egg-laying Mammals are monotreme species: the duck-billed platypus and four species of echidna (also known as spiny anteaters) Amphibians go through metamorphosis, mammals do not. Mammals also have hair and produce milk for their young
