Answer 1

Reptiles, such as snakes and lizards, have scaly skin, lay eggs with hard shells, and are usually cold-blooded, meaning their body temperature changes with the environment. In contrast, mammals have fur or hair, give live birth (most), and are warm-blooded, which means they can maintain a constant body temperature regardless of the environment.
