How do Hypotonic, Hypertonic, and Isotonic Solutions Affect the Water Movement of a Cell?
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...
