Question

The salt concentrations of cells of most marine organisms is higher than freshwater. Based on this fact, would the cells expand or shrink if the organism was placed in freshwater?

Answer 1

Expand

Step-by-step explanation:

Hypertonic solutions have less water (and more solute such as salt) than a cell. Seawater is hypertonic. If you place a cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside) But in this case you are doing the opposite so it should expand.

Hope this helps :)
