  1. Arboreal

  2. Fossorial

  3. Volant

  4. Terrestrial

Show answer
Correct Option: C
Explanation:

A number of animals have evolved aerial locomotion either by powered flight or by gliding. Animal that fly is a volant.

  1. Syrinx

  2. Pygostyle

  3. Furcula

  4. Quill feathers

Show answer
Correct Option: D
Explanation:
Besides pneumatic bones, another useful flight adaptation in birds is quill feathers. Each quill feather has a central stem or scapus. It is divided into a lower hollow part called the quill or calamus and a solid upper part termed rachis. Small filaments or barbs are attached to rachis. The barbs remain attached with one another to form a continuous blade for striking the air in flight.
So, the correct answer is 'Quill feathers'.

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

The adaptations for flight are called aerial adaptations. Many of a bird's bones are hollow which makes birds' bodies lightweight. Flying birds have large chest muscles that move the wings. Birds have feathers that help them fly. Fossorial adaptations are for those animals, which primarily live underground.

So, the correct option is 'False'.
