A

hypertonic, exosmosis

B

hypertonic, endosmosis

C

hypotonic, exosmosis

Text Solution

Verified by Experts

The correct Answer is:
A
In sea water, the surrounding water is salty and hence hypertonic to the body cells. Thus, water will move from its higher concentration (in body) to its lower concentration (sea water) leading to exosmosis. Therefore, manu fresh-water animals cannot live for long in sea water and vice versa.
