What additional experiments could you do with chicken eggs to test the properties of membranes discussed in this chapter? • Hospitals often inject fluid into patients' veins to increase blood volume. When they do, they use a 0.9% saline solution. Why do you think they use isotonic saline instead of distilled water?

Your friend notes that Gatorade has electrolytes like sodium and potassium chloride. He figures that if a few electrolytes are good for you, then a lot must be even better. Following this logic, he adds nearly a tablespoonful of salt to his Gatorade. What kind of solution is his Gatorade now (hypotonic, isotonic, or hypertonic)? What will likely happen to his cells if he drinks this liquid?
