A(n) _______ solution has a lower concentration of water than the cell placed in
the solution. - Answer- Hypertonic
When you receive fluid in the hospital, it is often 0.9% saline solution. What
would happen if the nurse used distilled water instead? - Answer- The distilled
water solution would be hypotonic to your blood cells, so they would gain water,
swell, and possibly burst.
When testing tonicity of red blood cells, if the solution became transparent after
adding blood cells, you could assume - Answer- the solution was hypotonic and
the cells had burst.
Which direction is the net movement of water when a cell is placed in a
hypertonic solution? - Answer- out of cell
Which of the following factors would increase the rate of diffusion? (Select all
that apply) - Answer-
-decreased molecular size
-larger concentration gradient
-thinner media
Based on the Movement of Water across a Selectively Permeable Membrane lab,
what is a selectively permeable membrane definition? - Answer- allows small

Two solutions are made by mixing sugar and enough water to make a 1 liter
solution. One contains 10% sugar and the other 20% sugar. Which solution has
more solvent? - Answer- 10% sugar solution
A semipermeable membrane is placed between two solutions. The membrane is
only permeable to water. On the RIGHT side is a 10% salt solution. On the LEFT
side is distilled water (100% water). In which direction will a net movement of
water occur? - Answer- LEFT to RIGHT
If blood cells are placed in a hypertonic solution, - Answer- the cells will shrink
due to water loss by the cell.
During osmosis water will move in which direction? - Answer- from the area with
lower solute concentration to the area of higher solute concentration
In the Tonicity of Red Blood Cells lab, you mixed whole blood with solutions of
different concentrations in order to - Answer- determine the tonicity of each
solution.
Small lipid soluble molecules would move through the plasma membrane by -
Answer- diffusion
