explore the concept of Osmosis using dialysis tubing and different concentrations of sucrose solutions‚ and to help one better understand what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis If the four dialysis tubes containing different concentrations of sucrose are all placed in their appropriate solutions for 20 minutes‚ then my predictions are as follows: The 1% in 1% sugar solution will keep a constant weight and stay the same size. The 1% in 50% solution

utilized in order to identify bacteria (Morello and Granato‚ 2003). In order to test for carbohydrate fermentation‚ tubed broths‚ containing a Durham tube for trapping any gas formed when the broth is incubated‚ are utilized (Morello and Granato‚ 2003). After incubation‚ a color change indicates that an acid product was formed‚ and a bubble in the Durham tube indicates that a gas was formed. In this study‚ carbohydrate fermentation tests for the presence of glucose‚ maltose‚ lactose‚ and sucrose in Proteus
