Question

If the dialysis tubing represents a cell membrane in this demonstration, what process is being observed in the changing color of the starch solution?

A) Osmosis
B) Diffusion
C) Active transport
D) Facilitated diffusion

Answer 1

In this demonstration, the changing color of the starch solution represents the process of osmosis, which is the transport of water through a semipermeable membrane from a region of high concentration to a region of low concentration.

Step-by-step explanation:

Osmosis, the diffusion of water across membranes from lower to higher solute concentrations, is being observed in the changing color of the starch solution in this demonstration. Osmosis is the transport of water through a semipermeable membrane from a region of high concentration to a region of low concentration.

This is different from dialysis, which is the transport of other molecules through a semipermeable membrane due to their concentration difference.

Dialysis, on the other hand, is the transport of any other molecule through a semipermeable membrane due to its concentration difference.
