Question

how would the contractile vacuole of a freshwater amoeba respond if the organism was placed in seawater? with more contractions with fewer contractions the contractions would suddenly cease with the same frequency of contractions

Explanation:

The contractile vacuole in a freshwater amoeba pumps out excess water that enters the cell by osmosis. Seawater is hyper - tonic compared to the amoeba's cytoplasm. So, less water would enter the amoeba in seawater, resulting in fewer contractions of the contractile vacuole as there is less water to expel.

Answer:

with fewer contractions
