Answer:
I would predict that the the following generation will have a large amount of pups that are eaten by the sharks.
This question seems like its asking about natural selection.
"Natural selection is the process when organisms better adapted to their environment tend to survive and produce more offspring"
Explanation:
If the marine biologist did not give the pups medicine in the first generation, the pups that were less fit or not adaptive to the enviroment to naturally survive the infections would have died. This would have prevented these pups from passing on their genes.
The next generation would consists of pups that are more immune to the sickness or more fit for their enviroment and might experiece less pups to die.
The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.
<h3>
What is fitness?</h3>
Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.
Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.
It is a way of measuring the individual ability to leave fertile offspring.
Aptitude must be significant to the natural selection act in its favor.
In the exposed example we can see the survival rate of two species.
The survival rate is telling us about the fitness of each species.
- The green beetle increases its survival rate (fitness) each year
- The brown beetle decreases its survival rate each year
These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
- There are two types of speciation: allopatric and peripatric.
- Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
- From the isolated population, new species are formed then it is known as the peripatric speciation.
- All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.
Answer:
Has three dominant alleles
Explanation:
Skin colour is a polygenetic inheritance and it is controlled by three genes pairs of alleles. The human skin is determined by the amount of melanin it contains. A combination of melanin producing alleles determines the skin color.
In the above question, the person has a skin color that is midway meaning only half of the alleles produced melanin. The total number of alleles is 6 and half of it is 3. So, only 3 alleles were dominant and the remaining three were recessive.
