**Experiment on Dialysis Bags and Starch Solutions**

In this experiment, dialysis bags were filled with various concentrations of starch and placed into beakers containing 15% starch solutions for 30 minutes. The membrane of the dialysis bags is not permeable to starch.

**Diagram Explanation**

Four beakers are illustrated, each with a different concentration of starch solution within the dialysis bags:

- **Beaker A:** The dialysis bag contains 1% starch.
- **Beaker B:** The dialysis bag contains 40% starch.
- **Beaker C:** The dialysis bag contains 15% starch.
- **Beaker D:** The dialysis bag contains 25% starch.

Each beaker is filled with a 15% starch solution outside the dialysis bags.

**Questions for Analysis:**

1. **Which of the bags is submerged in an isotonic solution?**  
   - An isotonic solution occurs when the concentration inside the bag equals the concentration outside. Identify which bag shows this balance.

2. **Which of the bags will lose water during the 30 minute period?**  
   - Identify which bags have a higher internal starch concentration than the external solution, resulting in water loss.

3. **Which bags are submerged in a hypotonic solution?**  
   - Hypotonic solutions occur when the solution inside the bag is less concentrated than the external solution, causing water to move into the bag.

Please fill in your responses based on the given information.
