1st container: isotonic solution, the concentrations of solutes that cannot cross the plasma membrane are the same on both sides of the membrane in this solution, * its equal
middle container: hypotonic, a solution that has a LOWER concentration of solutes than the cytosol inside the RBC's - water molecules enter the cells faster than they leave causing the RBC to swell and eventually burst *hemolysis
last container: hypertonic solution, has a HIGHER concentration of solutes than does the cytosol inside RBCs, water molecules move out of the cells faster than they enter causing the cells to shrink *crenation
