Limax maximus also known as the Great Slug is a species of slug in the family Limacidae.

This species of slug can be found in lawns, gardens, and other moist areas.

Limax maximus have omnivorous feeding habits. They are known to eat dead plants, fungi, other slugs, and also crops.

In an effort to control the slug population in local farms, some Florida farmers use a sodium chloride solution to kill the slugs on contact.

The skin of a slug is a semi-permeable membrane. How does the process of osmosis cause the body of the slug to dehydrate and eventually die?

The cells of the slug will take up liquid from the surrounding environment once the sodium chloride comes in contact with the skin.
The cells of the slug will take up liquid from the surrounding environment once the sodium chloride comes in contact with the skin.

The diffusion of water out of the cell will occur because there is a higher concentration of solute on the outside of the skin.

Ions of sodium chloride are carried across the skin by proteins in the membrane that act like pumps.

Answer 1

The correct choice is: "The diffusion of water out of the cell will occur because there is a higher concentration of solute on the outside of the skin."

Explanation: Salt on the slug’s skin creates a hypertonic environment outside the cells, so water moves out of the slug’s cells by osmosis toward the higher solute concentration, causing dehydration and death.
