Answer 2

Answer:

The earthworms possess a structure called as setae which helps them in locomotion.

Explanation:

An earthworm moves utilizing round and longitudinal muscles, just as fibers called setae. When the earthworm wants to move, it releases the setae from its body. The released setae act as anchor in the dirt.  

To push ahead, the worm utilizes its setae to attach the front of its body and pushes the longitudinal muscles to short its body. At that point, the worm stays the back of its body with setae and gets the circular muscles to extend its body. By this way the earthworm moves from one place to another.
