to aseptically transfer bacteria from an unknown to a tube of liquid broth. Answer: To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. Then you remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. Next‚ you have to pick up the inoculums or unknown culture by running the sterile loop or wire down into the tube. Once you get the inoculums‚ you drop it into the

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
