1. …within the cell

3.  Movement of molecules from a high concentration to low concentration.  why does this happen?  What is it called when concentration is the same throughout the area?

4.  Diffusion of water through a semi-permeable membrane

5.  What is a solvent?  A substance that dissolves a solute  How about a solute?  A substance that is dissolved in the solvent

6.  Why will a snail die if you put salt on it?

8.  Isotonic – same strength, equilibrium  Hypertonic – above strength, high amounts of solute  Hypotonic – below strength, low amounts of solute  Because cells are filled with salts and sugars, water will always want to move into the cell.
