Biology 100 Pre-lab Assignment #3 Lab Section and Group 1. For the diffusion and osmosis lab, you gathered data based on changes in the mass of model cells. To design your experiment, you made educated assumptions about what would pass through the dialysis tubing membrane, and what would not. Using the knowledge you gained during the macromolecules lab, specifically about the reagents that can be used to test for the presence of biological molecules, give examples of how you could have tested these assumptions in relation to movement of starch, glucose and protein (e.g albumin). These examples do not need to relate to the specific experiment your group did, and need only to address one biological molecule per example. (9 points)
