- 1. Transport of molecules in and out of the cell helps the cell maintain an internal balance called....
- 2. Passive transport moves molecules from an area of ___ concentration to low concentration.
- 4. When cells are placed in a ________solution, causes the cell to shrink, or shrivel up, as it loses water.
- 5. A characteristic of the fatty acid tails of the phospholipid that makes them tuck inside the membrane
