If human white blood cells were extracted from the circulatory system and then placed into an isotonic solution, which one of the following is most likely to occur?
A) Water will rush into the cells, and the cells will swell and eventually burst.
B) Because there is more water outside the cell than inside the cell, an equal amount of water will enter the cell and leave the cell.
C) There will be no change in the cells because the isotonic environment is in equilibrium with the cells.
D) Because a hypertonic environment is highly acidic, these cells will become acidic as well.
E) Water will diffuse out of the cells, and they will decrease in cell volume.
