Answer:
The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.
Explanation:
At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is
A=0.5
a=0.5
With those frequency, the expected percentage of offspring with dominant genotype will be:
AA= 0.5 * 0.5 = 0.25 = 25%
The number of homozygous dominant found is 35% which is higher than expected (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.
It can reduce it by 30 percent
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.
Biodiversity increases as the number of populations grow, because a greater population generally means a more diverse one.
However, this is not always true, so I'm not sure what answer they're looking for.
The best approach for Tyler is a controlled experiment if he wants to directly observe the outcome.
A controlled experiment is designed to minimize the effects of the variables other than the independent variable. A controlled experiment allows reliable results because he can do the experiment specific to the problem and variables involved.
