Question

based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water? the contractions would increase. the contractions would decrease. the contractions would cease altogether. the contractions would establish dynamic equilibrium.

Explanation:

The graph shows that as salt concentration decreases (moving from very high to very low), the number of contractions per minute increases. Distilled water has a very low salt concentration (even lower than the "very low" on the graph). So, based on the trend in the graph (negative correlation between salt concentration and contraction rate), when placed in distilled water (low - salt environment), the paramecium's contractions would increase.

Answer:

The contractions would increase.
