Question

Scenario Outside Solution Inside Cell (1% salt) Label the solution (hypo-/hyper-/iso-) Water Movement (→/←)
A 0% salt 1% salt ___


B 1% salt 1% salt 99%

C 10% salt 1% salt b

Answer 1

In this scenario, we are examining the relationship between the salt concentration of solutions in the external environment compared to the concentration inside a cell. The terms hypo-, hyper-, and iso- refer to the relative concentrations of solutes (in this case, salt) between the solutions.

**Scenario Analysis:**

**A:**
- Outside Solution: 0% salt
- Inside Cell: 1% salt
- Label the solution: **Hypotonic** (0% salt is less concentrated than 1% salt)
- Water Movement: **→** (Water moves into the cell)

**B:**
- Outside Solution: 1% salt
- Inside Cell: 1% salt
- Label the solution: **Isotonic** (Equal concentration inside and outside)
- Water Movement: **99%** (No net movement of water, but water moves in and out at equal rates)

**C:**
- Outside Solution: 10% salt
- Inside Cell: 1% salt
- Label the solution: **Hypertonic** (10% salt is more concentrated than 1% salt)
- Water Movement: **←** (Water moves out of the cell)

**Summary Table:**

| Scenario | Outside Solution | Inside Cell | Label the solution | Water Movement |
|----------|------------------|--------------|--------------------|-----------------|
| A | 0% salt | 1% salt | Hypotonic | → |
| B | 1% salt | 1% salt | Isotonic | No net movement |
| C | 10% salt | 1% salt | Hypertonic | ← |
