Cell Response to Hypertonic NaCl Solution

A human cell is immersed in a solution containing 0.1 M NaCl. This solution is isotonic to the cell's interior. You are conducting an experiment to observe the effects of varying concentrations of NaCl on the cell's homeostatic mechanisms.

After gradually increasing the NaCl concentration in the solution to 0.2 M, 0.3 M, and finally to 0.4 M, you notice significant changes in the cell's morphology and function. In particular, these changes include alterations in cell volume and ion transport mechanisms.

Which of the following best describes the physiological response of the cell to this hypertonic environment, specifically focusing on the mechanism it employs to maintain homeostasis?
