Suppose a cell's membrane is permeable to water, but not to Na⁺or Cl^-or any other solute. The NaCl concentration is higher outside the cell than inside the cell, and the osmolarity of the cell is higher than that of the solution surrounding the cell. What will occur? A) Overall, the cell will lose water. B) Overall, the cell will take up water, Na⁺, and Cl^-. C) Overall, the cell will take up water. D) Overall, the cell will take up water and lose Na⁺and Cl^-. E) Overall, the cell will lose water and take up Na⁺and Cl^-.

The cell will take up water because the osmolarity inside the cell is higher than outside, creating an osmotic gradient that drives water into the cell. Na⁺ and Cl^- cannot cross the membrane.
