When a fresh water protozoan is placed in marine water:
1 The contractile vacuole disappears
2 The contractile vacuole increases in size
3 A number of contractile vacuoles appear
4 The contractile vacuole remains unchanged
Explanation:
Contractile vacuole's job is to throw excess of water coming from outside to inside. In marine water, due to ex osmosis cell start loosing water anyway, means now there is need to preserve water not to throw it away. Therefore, contractile vacuole will disappear because presence of contractile vacuole will dehydrate the cell.
