Explain why dialysis tubing (partially permeable) can be used to model osmosis.
A
Dialysis tubing allows water through but not sucrose — models the partially permeable cell membrane; water enters by osmosis
B
Dialysis tubing allows all molecules to cross equally
C
Dialysis tubing uses active transport to move water
D
Dialysis tubing is only used to model diffusion, not osmosis
