Answer:
Step-by-step explanation:
- Osmoregulation is the process of maintaining the water and dissolved substances balance within a cell.
- To prevent excess water from entering the cell, amoeba expels water through a contractile vacuole.
- The contractile vacuole helps to remove excess water and maintain the concentration of dissolved substances inside the cell.
- Osmoregulation is essential for the amoeba to survive and function properly.
