Creating hypotheses based on observations. A hypothesis is a general principle or explanation that is derived from observations. Suppose you make the following observations: a. You look at 10 human liver cells and observe that each one has a nucleus. b. You look at 10 onion cells and observe that each one has a nucleus. c. You look at 10 nerve cells from a mouse and observe that each one has a nucleus. For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis. 1. The onion cells I looked at have a nucleus. F?2. All onion cells have a nucleus. T?3. All cells have a nucleus. T?4. Some cells have a nucleus. T?5. Only onion cells have a nucleus. T?6. If I look at 10 skin cells from my hand, each one will have a nucleus. T?

False True True False False True

Explanation:

A hypothesis is a supposition draw from data to carry an investigation or an argumentation.

1. The onion cells I looked at have a nucleus. False, even though the statement is true, is not a hypothesis because is not a supposition, it is rather an observation.

2. All onion cells have a nucleus. True, it is s a valid hypothesis because after the observation of 10 cells you draw a conclusion or supposition and affirm that all onion cells have a nucleus.

3. All cells have a nucleus. True, it is a valid hypothesis it contains a supposition derived from data observation

4. Some cells have a nucleus. False, the hypothesis is not valid because all of the observed cells contained nucleus not only some of them.

5. Only onion cells have a nucleus. False, after the observation of the different type of cells you see that they all had nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus. True, after the observation of different cells you can infer that if you look at your skin cells, they will have a nucleus.
