Questions: If cells are placed in an isotonic solution, Multiple Choice water diffuses out of the cells, and the cells shrink in a process called hemolysis water diffuses out of the cells, and the cells shrink in a process called crenation water diffuses into the cells and the cells swell, and eventually burst in a process called hemolysis water diffuses into the cells and the cells swell, and eventually burst in a process called crenation water diffuses in and out of the cells at the same rate, and the cells remain the same size

The answer is the last one: water diffuses in and out of the cells at the same rate, and the cells remain the same size.

Explanation for each option:

1. Water diffuses out of the cells, and the cells shrink in a process called hemolysis:

   • Incorrect. Hemolysis refers to the bursting of red blood cells due to water intake, not shrinking.

2. Water diffuses out of the cells, and the cells shrink in a process called crenation:

   • Incorrect. Crenation is the correct term for cell shrinkage due to water loss, but this occurs in a hypertonic solution, not an isotonic solution.

3. Water diffuses into the cells and the cells swell, and eventually burst in a process called hemolysis:

   • Incorrect. Hemolysis does involve cells swelling and bursting, but this occurs in a hypotonic solution, not an isotonic solution.

4. Water diffuses into the cells and the cells swell, and eventually burst in a process called crenation:

   • Incorrect. Crenation refers to cell shrinkage, not swelling and bursting.

5. Water diffuses in and out of the cells at the same rate, and the cells remain the same size:

   • Correct. In an isotonic solution, the concentration of solutes is the same inside and outside the cells, so water moves in and out at the same rate, maintaining cell size.

Summary: In an isotonic solution, water diffuses in and out of the cells at the same rate, and the cells remain the same size.
