Take a beaker and fill half of it with water. Put some wheat seeds in it, stir it and wait for some time. Which of the following holds true regarding the observation and inference of this experiment?

Options

A. Healthy seeds being lighter float on the surface of water.
B. Damaged seeds being lighter float on the surface of water.
C. Some healthy seeds and some damaged seeds float on the surface of water.
D. Damaged seeds being heavier settle down at the bottom.

Answer

**Step-by-Step Solution:**

1. **Set Up the Experiment:**
- Take a beaker and fill it halfway with water.
- Add some wheat seeds to the water and stir it gently.

2. **Observation After Waiting:**
- After waiting for some time, observe the behavior of the seeds in the water.

3. **Identify Seed Types:**
- You will notice that some seeds sink to the bottom while others float on the surface.

4. **Analyze the Results:**
- The seeds that sink to the bottom are likely to be healthy seeds. Healthy seeds are denser and have a solid structure, which causes them to sink.
- The seeds that float are likely to be damaged or hollow seeds. These seeds are less dense and have a poor internal structure, which makes them buoyant.

5. **Conclusion:**
- From the observations, we can infer that healthy seeds sink to the bottom due to their weight, while damaged seeds float on the surface because they are lighter and hollow.

6. **Final Answer:**
- The correct inference from the experiment is that damaged seeds float on the surface of the water, while healthy seeds settle at the bottom.
