Question

the solution is: hypertonic / hypotonic / isotonic
water will: not move / move into the cell / move out of the cell
the solution is: hypertonic / hypotonic / isotonic
water will: not move / move into the cell / move out of the cell
the solution is: hypertonic / hypotonic / isotonic
water will: not move / move into the cell / move out of the cell
the solution is: hypertonic / hypotonic / isotonic
water will: not move / move into the cell / move out of the cell

Explanation:

Step1: Recall tonicity definitions

Tonicity depends on solute - water concentration differences. Hypertonic: more solute outside cell. Hypotonic: less solute outside cell. Isotonic: equal solute outside and inside cell. Water moves from high - water (low - solute) to low - water (high - solute) concentration.

Step2: Analyze first case

In the first beaker, cell has 90% H₂O (10% solute) and solution has 63% H₂O (37% solute). Solution has more solute, so it is hypertonic. Water will move out of the cell.

Step3: Analyze second case

In the second beaker, cell has 50% H₂O (50% solute) and solution has 50% H₂O (50% solute). Solution is isotonic. Water will not move.

Step4: Analyze third case

In the third beaker, cell has 90% H₂O (10% solute) and solution has 80% H₂O (20% solute). Solution has more solute, so it is hypertonic. Water will move out of the cell.

Step5: Analyze fourth case

In the fourth beaker, cell has 82% H₂O (18% solute) and solution has 25% H₂O (75% solute). Solution has more solute, so it is hypertonic. Water will move out of the cell.

Answer:

1. The solution is: hypertonic. Water will: move out of the cell.
2. The solution is: isotonic. Water will: not move.
3. The solution is: hypertonic. Water will: move out of the cell.
4. The solution is: hypertonic. Water will: move out of the cell.
