Question

A marine fish has about 1% salt in his body. The ocean water is 3.5%. Will water move into or out of the fish?

Answer 1

the water will move out of the fish by osmosis  due to existence of concentration gradient .

Answer 2

Water will move out of the fish

Step-by-step explanation:

Osmosis is the process of the solvent moving from a less concentrated solution to a high concentrated one.

Here, ocean water has 3.5 % salt and marine fish has 1% salt in its body which means that ocean water has higher concentration of salt. Hence, water will follow the concentration gradient and move out of the fish.
