For each statement below, indicate "True" if it can be considered a valid hypothesis based solely on these three observations, and mark "False" if it cannot be considered valid.

1. The onion cells I examined contain a nucleus.

2. All onion cells contain a nucleus.

3. Every cell contains a nucleus.

4. Certain cells contain a nucleus.

5. Only onion cells contain a nucleus.

6. If I observe 10 skin cells from my hand, each one will contain a nucleus.

Answer:

1. The onion cells I examined contain a nucleus. false - this represents an observation based on the evidence you have collected.

2. All onion cells contain a nucleus. true - this qualifies as a valid hypothesis derived from your observations of onion cells

3. Every cell contains a nucleus. true  - this serves as a hypothesis since you examined 3 different cell types, taking several samples of each, and discovered they all possess a nucleus

4. Certain cells contain a nucleus. false - this cannot be seen as a valid hypothesis. The current evidence implies that all cells have a nucleus

5. Only onion cells contain a nucleus. - false, as you are aware this is incorrect because other cell types you examined also had a nucleus

6. If I observe 10 skin cells from my hand, each one will contain a nucleus. false - a hypothesis should be a broad principle that is supported by evidence; this statement is overly specific.
