When a freshwater paramecium is placed in salt water, it will most likely experience shriveling of the cell. This occurs because the salt water has a higher solute concentration than the internal environment of the paramecium, which leads to osmosis. Water inside the paramecium will move out into the salt water in an attempt to balance the solute concentrations. As a result, the paramecium will lose water, causing it to shrink and shrivel.
Question 23

swelling of the cell until it bursts
an increase in the action of its contractile vacuole shriveling of the cell
swelling of the cell until it becomes turgid
