1. Define diffusion.2. A glucose-starch solution was placed in dialysis tubing. Then, the tubing was placed in a cup containing IKI indicator. Did starch stay within the tubing or move out of the tubing? Did IKI indicator stay in the solution in the cup or move into the tubing? Support your answer with the observations.3. put the IKI solution in the cup and the contents of the dialysis tubing were tested with the glucose test strips. Did glucose stay within the dialysis tubing or move out of the tubing? Support your answer with the observations.4. How is a cell membrane similar to the dialysis tubing used?5. might it be inferred that:. a) starch and glucose molecules are the same size,
b) starch molecules are larger than glucose molecules, or
c) starch molecules are smaller than glucose molecules. explain your answer.6. How did hypotheses compare with outcomes?7. What is osmosis,8. Is osmosis a form of active or passive diffusion/transport? Why?9. Why do intravenous (IV) solutions need to have the same tonicity as blood?10. What occurred when blood mixed with solution? Why did this occur?11. Is the movement of substances in this exercise active or passive?
