Question

What happens if a marine protozoan is transferred to a freshwater medium?

• A. It bursts
• B. It shrinks
• C. It remain static
• D. None of these

Answer 1

The correct option is A It bursts

As we know that the fish absorbs oxygen with the help of gills.

When a marine animal absorbs water through its gills, some of the salts that are present in the water enters into the fish and it gets deposited inside of the fish.

So, the concentration of solute in fish is generally greater than the concentration of the freshwater. As a result of which animal will be kept in water then it will undergo osmosis and will undergo endosmosis and burst.
