STUDENT RESPONSE B
The cell shrivells and collapses in on itself. This is true because of osmosis. Osmosis occurs when the body of this water dwelling organism is taken out of equilibrium. The equilibrium is lost because the salt content of the salt water is much greater than that of the freshwater. The salt water is a hypertonic solution. Therefore water diffuses out of the cell through the differentially permeable membrane and into the salt water in order to create equilibrium. Ultimately, there isn't enough water inside the cell to create equilibrium and it dehydrates itself.
