Seal the end if it is not already closed. Next, pick up a pipette and fill it with glucose. (Use this pipette only for glucose) then release the glucose into the dialysis tubing. Place four more pipettes full of glucose into the dialysis tubing. Now it is time to get another pipette (not the one used for glucose) and fill it with starch and release it into the dialysis tubing. Repeat this 4 (four) more times until there is a total of 5 pipettes of glucose and 5 pipettes of starch in the dialysis tubing. Mix the solution. Next, seal the dialysis tubing completely and make sure there is little to no air left in the dialysis tubing. Rise the bag with water. Next, fill a 400ml beaker with 300ml of water. Add 5 pipettes of Lugol´s into the 300ml of water. Mix the solution gently. Place the dialysis tubing bag into the 400ml beaker and leave for 30 minutes. After 30 minutes remove the bag and record your findings. Get 3 test tubes and label them “control” “bag” and “beaker” Next fill an unused pipette with water and pour it into the control test tube. Open the dialysis tubing and fill a pipette of the solution inside using an unused pipette. Repeat again and pour into the bag test tube. Place two pipettes of the beaker solution into the beaker tube. Add one pipettes of Benedict´s into each tube Heat all tubes for three minutes. Record…

For unit 7.3 the experiment needed 2 microfuge tubes one labeled "L" for lactose and the other labeled "M" for maltose. The experiment also called for a total of 3 clean plastic pipettes. With one pipette add milk up to the 0.5 line of the lactose tube. With the second clean pipette add maltose solution up to the 0.5 line of the maltose tube. With the third clean pipette, add lactase solution to each tube, until the level of mixture in each tube comes up to the 1.0 line of the tube. Place both tubes in the 40 degrees celsius water bath and incubate them for 10 minutes. The other thing needed is glucose strips. After the tubes have been incubated for 10 minutes, place a glucose strip in each tube for one second. Let it sit for thirty seconds, then compare to the chart provided. For unit 7.4 the experiment called for two microfuge tubes. One labeled "control" and label another one "EDTA". Add 1.25 mL of EDTA to the EDTA tube, add 1.25mL of distilled water to the control tube. Add 3 drops of milk to each tube, invert the tube and let sit for 1 minute. Then add 3 drops of lactase solution to each tube. Then place both tubes in the 40 degrees celsius water bath and leave them for 10 minutes. After the 10 minutes are up, place the glucose strip in each tube and let the strips sit for 30 seconds. Then compare to the charts provided.…
