Questions: 1) What changes do you notice in the final state of the beaker? Initial state Final State 2) Why is there starch indicator solution inside of the dialysis tubing ? 3) Explain why starch did not get out of the tubing into the water in the beaker. 4) What color do you expect to see inside of the dialysis tubing in the beaker? Why? 5) Glucose is a simple sugar substance. Explain how you can determine if it diffused out of the membrane into the water with the starch indicator solution. Extended responses - real-life context and experimental eror 6) In many animals, glucose, rather than starch, is transported by the blood through the body to all the cells. Starches in many foods are digested to yield glucose. Based on what you learned in this laboratory activity, explain why the digestion of starch to glucose is necessary 7) During Part A of this laboratory activity, one group of students followed the directions incorrectly. They poured the Starch Indicator Solution into the "cell" and filled the beaker with starch and glucose solution. State how their results would differ from those obtained by students in their class who followed the directions correctly.

Can you do the first 2 question for me please
The experiment Part A- Model cell For the first part of the experiment, glucose and starch were placed in a tied dialysis tubing. The tubing is selectively permeable. The tubing was placed in a beaker with water and starch indicator solution (iodine) for 20 minutes. Starch is a complex substance and cannot pass through the membrane, the starch indicator solution is simple and can pass through the selectively permeable membrane.
