Respuesta :

The correct answer is A.
Replace the concentration description with actual values. Paramecia that lives in salt water they have the hypertonic environment to mean that the cell has a need for water. Therefore, the contractile vacuole can release more water into the cell.
Paramecia that lives in freshwater they live in the hypotonic environment and it calls for contractile vacuole which helps to pump out the excess water.
A is the correct answer on e2020
