The salinity of a small inland lake has recently started to increase. Researchers are planning to study the lake over several decades to investigate how freshwater organisms survive significant changes in their natural habitat. Which of the following physiological mechanisms will the researchers most likely observe among the surviving organisms in the lake?

If the salinity increases, the cells will be subject to a hypertonic solution. Cells would lose water in this condition. Organisms will want to counter the movement of water from the cell to the environment.
