Answer 2

Mammals and egg-laying animals

Explanation:

Mammals incubate the embryo inside their body and give birth to the young ones. Birds and Reptiles usually lay eggs as they don't have mammalian glands and don't milk their young. Mammals have fur and hair while reptiles have scales. Egg-laying animals lay their egg and the fertilized egg incubates the embryo until it is mature enough to hatch and start a new life.

Mammals: Cow, Deer, Cat, Tiger, Dog

Egg-laying: Ostrich, Frog, Lizard, Snake, Hen.
