Give scientific reason. 'Fish can easily swim in water.'
Answers
Answer:
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. 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. Fish have 5 types of fins. They are the pectoral, pelvic, dorsal, anal and caudal fins.
Fish can easily swim in water as their structure and internal organs are all conducive to it.
Explanation:
- Fishes have gills with which they can breathe and extract out oxygen from water.
- Their body shape is such that they can swim with the least resistance in the water. Their eye shape and eyes are built so that they can see underwater at all times.
- Their skin is built in a way that is suitable for staying underwater forever. It can be safely concluded that the entire biology of fish is so that they can swim easily in water and make it their natural habitat.
