a. It assumes that the natural world works according to rules that do not change unpredictably.
<span>Scientists utilize and make use of the scientific method in order to have clear basis and evidence for their investigations. Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation</span>
2. Hypothesis
3. Experimentation
4. Interpretation of data
5. Evaluating the data
6. Passing and recording the data
<span>These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.<span><span> </span>

Answer:
Option B, No
Explanation:
Complete question is as follows -
You have spent time working with a population of beetles. Sexually mature males range in size from 2-6 cm in length. You realize that the females only mate with males that measure less than 3 cm long. If you measured allele frequencies at a single gene (locus) that contributes to overall length, would you expect this population to be in H-W equilibrium from one generation to the next?
Select one:
a. Yes
b. No
Solution -
No, because Hardy Weinberg’s equilibrium theory is not applicable in practical scenario as it assumes that H-W equilibrium persists from one generation to the other only when these is no disturbing factor . These disturbing factors include – natural selection, non-random mating, genetic drift, gene flow and mutations. Since this theory works only in an idealized state where no such disturbances occur, it is very difficult to say that the beetle population can remain in H-W equilibrium. Also the females in the beetle population are selecting the males for mating thereby exhibiting sexual selection. Hence, H-W equilibrium will not be applicable.
Hence, option B
Answer:
Option B, The controls on cell growth and divisions can be turned on and off
Explanation:
There are signal proteins that control and regulate the cell growth and division process. For instance, mitogens help in removing the negative controls which would otherwise have blocked the cell cycle progression. Then there are growth factors that synthesize proteins and hence stimulate cell growth. Also there are some survival factors that suppress the apoptosis. Based on these three factors the cell division and growth can be turned on or off.
Hence, option B is correct
You only got one point because it is need of more detail. Hope this helps!
