Q. 2. (B)Distinguish between the following
pairs:[4]
1.Adaptation in birds and fish​

Answer 1

Answer:

Many of the bones in a bird's body are hollow, making the bird lightweight and better adapted to flying. Birds also have feathers that make flight easier. Long feathers on the wings and tail help birds balance and. Fish have gills that allow them to “breathe” oxygen in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water as it passes over them. Fish have a stream-lined body. IT IS A LONG DETAILED QUESTION BUT YOU CAN WRITE IT SHORT IN YOUR OWN WORDS.

Hope it helps!
