If the sodium ions could not move into the cells, how would this affect the movement of water?
A) Water would leave the intestines and enter the cells by diffusion.
B) Water would leave the intestines and enter the cells by osmosis.
C) Water would leave the cells and enter the intestines by diffusion.
