what is the negative control in the membrane stability experiment and what is the negative control in the osmosis experiment?
Wator Dialysis Tube Sucrose Solution Part 1 pare 6 beakers and 6 dialysis bags as described below. Your instructor wil as not to have any leaks. as not tot nte hnew to prepare the dialysis bags. Be very careful when preparing bags Unknown sucrose Bag H20 0.5 M sucrose 1.5 M sucrose 1.0 M sucrose 150 mL 150 mL 150 mL 150 mL H20 Beaker 150 mL 150 mL H20 H2O 1.5M sucrose H20 A stock of 1.5 M sucrose and an unknown concentration of sucrose You'll need to make the dilutions for the other concentrations before adding them i the bag Which bags are isotonic to the beaker? Hypotonic? Hypertonic? Record this in your notebook will be provided to - - Record the weight of each bag in your notebooks, then simultaneously submerge all é6 bags in the appropriate beaker Every 10 minutes, record the weight again for each bag. Repeat this for at least 30 minutes Once you've finished your readings, plot a graph of change in weight vs time for all 6 bags Part 2 Prepare the following tubes: Tube 1: 0.5g of yeast in 5mL of H20Explanation / Answer
Negative control in the osmosis experiment:
Movement of solvent from high concentration to low concentration with permeable membrane .
Negative control in the membrane stability experiment
Treatment of heat to the plasma membrane.
