Question

Quizplus · Accepted Answer

Amphibians lay their eggs in water for external fertilization, and their eggs lack an amnion, a membrane that protects embryonic cells from dehydration. This means that amphibian eggs have to be in a moist environment, such as water or damp soil, to prevent them from drying out. Additionally, amphibians have moist, permeable skin that is thin and lacks a waterproof layer, which allows for gas exchange but also makes them vulnerable to dehydration on land. Therefore, amphibians are adapted to live close to water bodies to maintain their high moisture requirements.
