question 10 (1 point)

1. draw an arrow to show which direction solvent will diffuse across the membrane.

0.3 osm cell
0.5 osm solution
water will flow 1

1. what will happen to the cell ? ____2
2. is this dialysis, osmosis, or neither ? 3

a. into the cell b. out of the cell c. neither, an equilibrium
d. shrinkage e. swelling f. dialysis g. osmosis

Explanation:

1. Osmosis is the movement of water from an area of lower solute concentration (0.3 osM cell) to an area of higher solute concentration (0.5 osM solution). So water will flow out of the cell.
2. When water flows out of the cell, the cell loses volume and undergoes shrinkage.
3. Osmosis is the specific process of water movement across a semi - permeable membrane (like the cell membrane in this case) based on solute concentration gradients. Dialysis is a more general process of separating substances based on molecular size across a membrane (not relevant here as it's specifically water movement based on concentration).

Answer:

1. B. out of the cell
2. D. shrinkage
3. G. osmosis
