4. If you take a cell with a 9% solute concentration in the ICF and place it in an ECF of 12% solute concentration, explain what will happen to the cell

The correct answer is - water exit from the cell.

Explanation:

In this case, the ECF contains a higher concentration of solutes than the cytosol of the cell. This will result in having a lower concentration of water as compared to the ICF.

It is the hypertonic condition where the concentration of solute inside the cell is less than outside of the cell that means the water concentration is higher inside the cell than outside the cell so by the process of osmosis. in osmosis water move from a high concentration area to a low concentration area.
