Abiologist discovered a young, four-legged animal. the animal had lungs, seemed to fertlize internally, and its outer surface was covered with scales. in which class of animals is the biologist likely to place the animal?

3. They breathe with the aid of lungs

4. Although most reptiles lay eggs, some also give birth to live young (fertilise internally)!
