Ans: The skeleton of a bird is well-suited for flying because the wings of the birds are attached to their thorax. Also, their light organs like the lungs and the sacs are at a higher position. The position of their heavy muscles lies in the center of their body. Due to the structure of the body of a bird, the air resistance is also reduced. In this way, a bird’s skeleton is well suited for flying.

19. In Fig. 8.2 There are two snakes of the same size slithering on the sand. Can you identify which of them would move faster and why?
