26 An osmosis investigation was conducted using chicken eggs to represent cells with semipermeable membranes. The mass of each egg was measured to determine how much water diffused into or out of the eggs. The eggs were first soaked in vinegar to dissolve the shell. Each egg was then placed in one of three different solutions for 24 hours. The table below shows the results of the investigation. Based on this Egg Osmosis experiment, which of the following should be inferred about cells with semipermeable membranes?

27 Analyze the data from the Egg Osmosis experiment to determine which of the following statements best describes the egg when placed in the Corn Syrup solution.

28 Analyze the data from the Egg Osmosis experiment to determine which of thefollowing statements best describes the egg when placed in Distilled Water solution.
