The type of solution that causes water to rush into the cell is what type of solution? 1) O Isotonic
2) Hypotonic
3) Selectively permeable
4) O Hypertonic

The type of solution that causes water to rush into the cell is hypotonic (option 2).

Explanation:

When a cell is in a hypotonic solution, it tends to incorporate water into its interior, through a process called osmosis.

Osmosis refers to the movement of water molecules from a medium with a lower concentration of solutes to another with a higher concentration, passing through a semi-permeable membrane.

In osmosis, the difference in concentration creates an osmotic gradient, whose force determines the movement of water towards the solution with the highest concentration of solutes, until the concentrations are equalised. When equilibrium is reached, the osmotic gradient disappears.

The other options are not correct because:

    1. An isotonic solution is in equilibrium with the cell and does not produce water movement.

    3. Selectively permeable refers to the membrane that allows the passage of some substances and prevents the passage of others.

    4. Hypertonic: if the medium is hypertonic, the water leaves the cell and does not enter it.
