A scientist creates an artificial cell with a selectively permeable membrane allowing only water to pass and injects a 5 M glucose solution. What effect would you expect to observe after an hour?

In the scenario presented, the artificial cell has a selectively permeable membrane that allows only water to pass through, while the glucose solution remains on the outside. The principle at play here is osmosis, which is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Since the outside solution is a 5 M glucose solution, it is hypertonic compared to the interior of the artificial cell, which likely has a lower concentration of solutes (assuming it contains mostly just water). Therefore, water will move from inside the cell, where there is a higher concentration of water (and lower concentration of solutes), to the outside where the concentration of solutes (glucose) is higher.

This movement of water into the hypertonic solution will continue until there is an equilibrium reached, or until the concentration of solutes becomes equal on both sides of the membrane. Therefore, you would expect to observe that water moves into the cell from the outside environment over the course of an hour.
