Answer:
a) Amphibians are tied to water for reproduction, while reptiles have amniotic eggs that can survive on dry land.
Explanation:
Amnion is the membrane surrounding the fetus. Animals that posses amnion are termed as Amniotes. Amniotes are tetrapods (i.e descendants of four-limbed and backboned animals) that are characterised by having an egg equipped with an amnion, an adaptation to lay eggs on land rather than in water
Amphibians reproduce sexually with either external or internal fertilization. Amphibians do not produce amniotic eggs, so they must reproduce in water.
Unlike amphibians, in reptiles production of amniotic eggs takes place. The shell, membranes, and other structures of an amniotic egg protect and nourish the embryo. They keep the embryo moist and safe while it grows and develops in mos dry lands.
