explanation the movement in earthworm.
Answers
Answer:
An earthworm moves using circular and longitudinal muscles, as well as bristles called setae. The earthworm can push the setae out of its body to grab the soil around it. To move forward, the worm uses its setae to anchor the front of its body and contracts the longitudinal muscles to shorten its body.

Answer:
• An earthworm moves using circular and longitudinal muscles, as well as bristles called setae. The earthworm can push the setae out of its body to grab the soil around it. To move forward, the worm uses its setae to anchor the front of its body and contracts the longitudinal muscles to shorten its body.Then the worm anchors the back of its body with setae and contracts the circular muscles to lengthen its body. The result is that the worm inches forward. In this lesson, you will use servo motors to model this movement.
• The movement in earthworm is called peristalsis. During movement the earthworm first extends the front part of the body, keeping the rear portion fixed to the ground. Then,it fixes the front end and releases the rare end.It then shortens the body and pulls the rare end forward. This makes it move by a small distance.
• An earthworm does not have bones. It has muscles that help to extend and shorten the body.Repeating such muscle expansions and contractions, the earthworm can move through soil. The body secretes a slimy substance to help the movement.
