Question

the data in the graph are the result of a paramecium being placed in a hypertonic salt solution. paramecium contractile vacuole contractions based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water?

Explanation:

Step1: Analyze the graph trend

As salt concentration increases, the number of contractile - vacuole contractions per minute decreases.

Step2: Consider distilled water

Distilled water has a very low salt concentration.

Step3: Predict the result

Based on the graph trend, at very low salt concentration (like in distilled water), the number of contractile - vacuole contractions per minute would increase.

Answer:

The number of paramecium contractile - vacuole contractions per minute would increase.
