Question continued
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.
