how would the contractile vacuole of a freshwater amoeba respond if the organism was placed in seawater?\nwith more contractions\nwith fewer contractions\nthe contractions would suddenly cease\nwith the same frequency of contractions
Answer
Brief Explanations:
The contractile vacuole in a freshwater amoeba expels excess water that enters the cell due to osmosis (freshwater is hypotonic to the amoeba's cytoplasm). Seawater is hypertonic compared to the amoeba's cytoplasm. When placed in seawater, less water will enter the amoeba by osmosis. So, the contractile vacuole will have less water to expel and will contract fewer times.
Answer:
with fewer contractions
