This means only certain materials will be allowed to enter and exit through the egg’s membrane. The purpose of this experiment is study the process in which water molecules pass the egg membrane‚ osmosis. This experiment also gives insight on how other ‘semipermeable membranes’ work‚ like a model for other membranes similar. If 3 eggs are immersed in 3 different

Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and
