7. 6. If a cell contains 85% water and is placed into a environment which is 50% water. Is the cell hypotonic or hypertonic? In which direction will the water move, into the cell or out of the cell?

8. 7. A cell contains 85% water and is placed into a solution which contains 90% water. Is the solution in the environment hypotonic or hypertonic? In which direction will the water move?

9. 8. If a cell which contains 90% water is placed into an isotonic solution, what percentage of the solution is water?

10. 9. A cell contains 95% water, the environment outside the cell contains 45% solutes. Is the cell in a hypotonic or hypertonic environment?

11. 10. A cell containing 25% solutes is placed into a solution which contains 35% solutes. Which direction will the water move, into the cell or out of the cell?
