Bio 103 Lab 4: Diffusion and Osmosis EXAM Questions &
Answers | Latest Already Graded A+ UPDATE 2025|2026 !!
Did diffusion across the membrane occur for the glucose
solution? - ✔✔Yes
Did diffusion across the membrane occur for the iodine
solution? - ✔✔Yes
Did diffusion across the membrane occur for the starch
solution? - ✔✔No
How do you determine if iodine and/or starch diffuse across
the dialysis tubing? - ✔✔If only iodine is able to diffuse across
the membrane, the solution in the dialysis tubing bag will look
dark purple
In the osmosis lab, why was it called a selectively permeable
membrane? - ✔✔It allows small molecules, such as water, to
pass through but not larger molecules, such as corn syrup
What can you conclude about the diffusion of iodine, glucose,
and starch across the selectively permeable dialysis tubing
membrane? - ✔✔Diffusion occurred based on molecular size.
