Answer 1

Reptilians

Step-by-step explanation:

Reptiles have scales, which form a protection against dehydration for the animal, the skin of reptiles is impermeable due to the intense production of keratin.

Moreover, the reproductive system of reptiles is an important factor of adaptation of these animals to the terrestrial environment.

Reptiles reproduce through internal fertilization, where the male introduces sperm into the female's body.

The main characteristic of reptilian eggs is that they are amniotic, in other words, they contain within their structure amnion, a liquid that provides protection against mechanical shocks and prevents dehydration of the reptilian embryo.
