In which situation would water enter a cell through osmosis? A. The cell is 20% water, and the cell's environment is 80% water,
B. The cell is 50% water, and the cell's environment is 50% water,
C. The cell is 60% water, and the cell's environment is 40% water.
D. The cell is 80% water, and the cell's environment is 20% water.

A

Explanation:

Water enters osmosis when the cell's water is lower than its environment's water. This is known as Hypertonic. B is an equalibrium so nothing special happens there, and C and D are examples of potential bursting of the cell from too much water, known as Hypotonic, so in process of elemination, A would be the answer. Another way of telling that C and D aren't the answer is that if they were really true, both of them would be correct, and there can't be two correct answers.
