Type the answers, print them out, and turn them in at the BEGINNING of lab. Part I: Define the following. 1. Diffusion 2. Concentration gradient 3. Equilibrium 4. Osmosis 5. Hypotonic 6. Hypertonic 7. Isotonic 8. Tonicity 9. Crenate 10. Lyse 11. Active process 12. Passive process 13. Carrier mediated 14. Solute 15. Solvent Part II. 1. Diffusion is a concentration to a process where a solute moves from a concentration. 2. Osmosis is the movement of concentration to a solution with a from a solution with a concentration. 3. Isotonic saline and 5% dextrose in water are solutions considered isotonic to human blood. What effect on red blood cells would you expect if a patient were given these fluids intravenously? A solution of 10% dextrose in water is hypertonic to human blood. What would happen if you were to infuse your patient with this solution? 4. Gatorade and other sports drinks are actually hypotonic solutions. How do these drinks rehydrate their user’s cells? 1
