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.
As there are no answer choices, I'm going to answer this just based off my knowledge
Analogous structures suggest convergent evolution because they have both evolved from a set of species but for different reasons and from different causes.

Answer:
The answer is a heme cofactor.
Explanation:
Peroxidase is an enzyme that catalyzes oxidation/reduction reaction by using hydrogen peroxide as a substrate.
Donor+H2O2 ↔ Oxidized donor + H2O
Peroxidase active site can contain a heme cofactor that has an iron ion and a porphyrin molecule that acts as an electron donor to the hydrogen peroxide which is then reduced to water.
