Question

Explain how fishes and ships are suited to move through water

Answer 1

Answer:

Gills absorb oxygen from the water as it passes over them. ... They use some of their fins to propel themselves through the water and others to steer the body as they swim. Fish have a system of muscles for movement. Muscle contractions ripple through the body in waves from head to tail.

Answer 2

Explanation:

Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. This motion moves them forward through the water. Fish use their back fin, called the caudal fin, to help push them through the water. The fish's other fins help it steer.
