2. All onion cells have a nucleus. True, it is s a <u>valid hypothesis</u> 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<u> valid hypothesis</u> it contains a supposition derived from data observation
