Recall that the cuticle seals plant surfaces and plants conserve water, and the seed derived plant groups to reproduce effectively on dry land. the analogous adaptations in reptiles are (analogous to the cuticle) and (analogous to the seed).

The equivalent versions in reptiles are scales (analogous to the cuticle) and the amniotic egg (analogous to the seed). Recall that the cuticle seals plant surfaces and helps plants conserve water, and the seed helps derived plant groups to reproduce effectively on dry land.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
