Answer 2

Answer:

Explanation:

Earthworm:

The earthworm first fixes its reared end using bristles called setae. Then it extends its body forward. It fixes the front end and releases the rear end. Then it pushes the rear end towards the front. This continues as the earthworm eats its way through soil.

Snake:

The snake has a long backbone. It moves through many loops. Each loop gives a forward push by pressing against the ground. So, the snake can move quickly without going in a straight line.
