Question

How would the contractile vacuole of a freshwater amoeba respond if the organisms was placed in seawater

Answer 1

Well, It would be placed in a hyper tonic solution and will shrink. Hope this helped!

Answer 2

Answer: The contractile vacuole will shrink, expelling more water, thereby causing the cell to shrivel.

Explanation:

The main function of the contractile vacuole is to regulate the amount of water in the cell and to expel waste products. When a freshwater amoeba is placed in seawater which is hypertonic, the contractile vacuole will release more water in response to the concentration gradient thereby making the cell to shrivel up.
