Question

question 5. which statement best describes the conditions in which the contents of the cell and its environment are isotonic? a. in an isotonic environment the cell would lose mass and therefore would be in a solution 0.7m or below b. in an isotonic environment the cell would gain mass and therefore would be in a solution 0.6m or above c. there is insufficient data in the graph to determine if the solution is isotonic d. in an isotonic environment the cell would not change its mass and therefore would occur in a solution at approximately 0.65m

Explanation:

In an isotonic environment, the solute - concentration outside the cell is equal to the solute - concentration inside the cell. There is no net movement of water across the cell membrane, so the cell does not change its mass.

Answer:

D. In an isotonic environment the cell would not change its mass and therefore would occur in a solution at approximately 0.6M
