Which way will water molecules move if a red blood cell is placed in distilled water?.

Stels [109]

Answer:

If you put a red blood cell in distilled water (100% H2O), there will be a net movement of water from a region of higher concentration (100%) to a region of lower concentration (the cell with 99.15% H2O). The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic (it contains less salt than the red blood cell) to the red blood cell. The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis.
