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 <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
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.
The way that I know it is that cells make up tissue, tissue makes up organs, and organs make up organ systems.
Answer:
30 minutes
Explanation:
Bacteria reproduce by binary fission, a process by which one parent cell divides to form 2 progeny cells. Because one cell produces 2 progeny cells, bacteria are said to undergo exponential ( logarithmic) growth.
As in the case of staphylococcus aureus, we start with 100 cells , and after 90 minutes number becomes 800 that means , firstly the cells doubled (100 x 2 = 200 ) after 30 minutes. Again after 30 minutes they doubled ( 200 x 2 =400 ) and again after 30 minutes they doubled (400 x 2 = 800). So in 90 minutes 100 cells became 800 cells.
Hence the generation time for S.aureus is 30 minutes.
