Question

for each of the following, do these things. determine the solute and solvent for the solution outside the cell (environment) and for the inside of the cell. then... a. tell whether the solution outside the cell is hypotonic, hypertonic, or isotonic. b. give the direction of the net movement of water (into cell, out of cell, or into & out of cell at equal rates). c. tell what will happen to the cell (shrink, swell, or stay the same). 20 % solute % solvent 80 % solute % solvent 1. % solute 10 % solvent % solute 90 % solvent 40 % solute % solvent 30 % solute % solvent a. b. c. a. b. c. a. b. c.

Explanation:

Step1: Recall definitions

A solution is a mixture of solute and solvent. In osmosis, water moves from an area of high - solvent (low - solute) concentration to an area of low - solvent (high - solute) concentration. Hypotonic: lower solute concentration outside the cell; Hypertonic: higher solute concentration outside the cell; Isotonic: equal solute concentration inside and outside the cell.

Step2: Analyze first case (20% solute inside, 80% solute outside)

• A. Inside the cell: 20% solute, 80% solvent. Outside the cell: 80% solute, 20% solvent.
• B. The solution outside the cell is hypertonic (higher solute concentration outside).
• C. Water will move out of the cell, and the cell will shrink.

Step3: Analyze second case (90% solvent inside, 10% solvent outside)

• A. Inside the cell: 10% solute, 90% solvent. Outside the cell: 90% solute, 10% solvent.
• B. The solution outside the cell is hypertonic.
• C. Water will move out of the cell, and the cell will shrink.

Step4: Analyze third case (40% solute inside, 30% solute outside)

• A. Inside the cell: 40% solute, 60% solvent. Outside the cell: 30% solute, 70% solvent.
• B. The solution outside the cell is hypotonic (lower solute concentration outside).
• C. Water will move into the cell, and the cell will swell.
