Question

slugs are common garden pests. they have skin that is semipermeable and moist. the most common way to rid a garden of slugs is by applying salt to them. why does this work? a sodium chloride will move from an area of higher concentration to an area of lower concentration. b the slugs will take up water from the environment and explode. c water inside the slugs cells will diffuse out of the cells because there is a greater concentration of salt outside than inside the cells. d sodium ions are carried outside the skin by an ion pump

Explanation:

Slugs have semi - permeable skin. When salt is applied, a hypertonic environment is created outside their cells. According to the principle of osmosis, water moves from an area of lower solute concentration (inside the slug's cells) to an area of higher solute concentration (outside the cells where salt is applied).

Answer:

C. Water inside the slugs' cells will diffuse out of the cells because there is a greater concentration of salt outside than inside the cells.
