Please explain to me how to do this?

the answer is all about hypertonic, hypotonic and isotonic solutions and how the red blood cells will react when put into each solution. if the cell is put in a solution that has a stronger concentration of solutes than in the blood cell it will shrink or crenate. the solution in cell comes out in attempt to equalize the percentage of solutes both inside or outside the cell. this is the hypertonic solution. if the cell is put in to a hypotonic solution having less solutes this will cause the cell to expand becoming turgid or firm and eventuall bursting. in an isotonic solution the cell stays the same because solutes both inside and outside the cell dont change.
