An answer might be - <span>Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

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.
Answer:
25%
Explanation:
use a punnet square, it shows that the dominant trait will give the offspring 75% chance of having the non pink hair phenotype
because that is where the sperm divide to multiply
Answer:
Positive natural selection.
Explanation:
The positive natural selection is a type of natural selection that increases the frequency of an allele or trait when it is advantageous for the population. What happened in the example is that the mouth with the slight change in morphology (trait) was more advantageous for the population in the south in relation to the ancestral morphology (still preserved in the population in the north), and therefore its frequency increased. This, in turn, is due to the fact that the food (prey) is not the same in the two habitats (north and south). The specific prey in the south, caused the new morphology to be selected, (increasing the frequency of individuals with the new mouth), becasue probably that trait allows the trouts in the south to hunt more effectively.
