3. A red blood cell is placed in pure water where the extracellular fluid contains 0% salt, while the intracellular fluid of the red blood cell contains 0.9% salt.
Will it shrink, swell, or remain the same?
What direction does water move, and why?
It will swell, water is moving into the cell because its moving from an area of high concentration to low concentration
