Answer 1

In zoology the organisms are classified under the animal kingdom based upon their similarities in the structure, characteristics and behavior. The birds belong to the class Aves. Whereas the human and the animals belong to the class of mammals.

Complete step by step answer:
A) Aves & Mammals:
Both the Aves and the mammals possess back bones and they are called vertebrates and they are warm blooded animals. They possess the four chambered hearts. They also provide parental care to its young ones. The blood of these organisms has both red blood cells and the white blood cells in their body.
b) Turtle & snail:
These two animals have the very strong shell on their back and these shells are used for the purpose of protection from the predators or any other environmental dangers. They both live inside their shells and remain dormant when there are the extreme hot and cold climatic conditions. These two animals are poikilotherms which means they have no ability to maintain their constant body temperature. And hence they are cold blooded organisms.
c) Frog & crocodile:
They are oviparous animals. These both the organisms use lungs for the process of respiration and they are both terrestrial and aquatic organisms. Both are egg laying animals. They both possess very hard and dry skin. The epidermal layer of both the frog and the crocodile is called scales.
