Define the terms resolution and illumination. Identify its characteristic functional groups of an amino acid. State the equation for the total magnification of the compound microscope. Now hopefully some good answers to this lab practice test. Different student answers could be acceptable.
Diffusion is the movement of materials from a higher concentration to a lower concentration.
The glucose diffused from the membrane. This was proven because the glucose test strip turned from yellow to green in the cup or beaker. Iodine which was placed in the water in the cup diffused into the membrane. We know this because the starch inside the membrane bag turned blue-black. Starch did not diffuse from the bag as if it had, the iodine in the water outside the bag would have turned blue-black.
