Question

The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.

Answer 1

Answer:

The contraction would increase.

Explanation:

The contraction would increase if the paramecium were placed in distilled water because of the change in the surrounding environment. The contractile vacuole will expel water less frequently because there is higher concentration of water outside the cell whereas the solute diffuses due to lower concentration of salt in the solution. So due to change of environment from saline solution to distill water solution, the contraction increases in the paramecium.
