Question

1. How do (i) earthworm (ii) fish (iii) snake move?​

Answer 1

Answer:

1. Skin

2. Fins

3. Scales

Explanation:

1.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.

2.Fish swim by flexing their bodies and tail back and forth. Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. ... Fish use their back fin, called the caudal fin, to help push them through the water. The fish's other fins help it steer.

3.Snakes typically swim, climb or crawl by bending their spine into serpentine coils or using the leading edges to push off objects. An extreme example of their diversity of movement gives the sidewinder rattlesnake its name.
