Answer:
The correct answer is option B "It will become narrower (span a more narrow range of ambient temperatures)".
Explanation:
Dogs, and other animals with fur, use their pelage to increase the range of ambient temperatures that they can tolerate. The way they do it is by altering their fluffiness depending if they are exposed to cooler or heater temperatures. If a dog is shaved, its thermoneutral zone will become narrower. Therefore, the dog will not be able to live in extremal temperature conditions as it did before with its fur.
Answer:
e. is under purifying selection
Explanation:
Purifying selection removes deleterious alleles that can arise through
random mutations
.
Mutations may or may not have consequences at the level of genetic expression depending on whether those mutations are synonymous or nonsynonymous. Synonymous mutations do not generate changes in the protein to be encoded while non-synonymous ones do.
Important genes for the development of the organism - such as those involved in the neural development- are very likely to be under purifying selection, eliminating individuals with deleterious alleles since those alleles (product of non-synonymous substitutions) do not allow the individuals to survive.
<span>The mechanism of descent with modification is known as "evolution". This idea of descendants of adult species being similar in most ways to their ancestors but slightly modified in some way is the basis of an entire belief system for some. For example it is not unreasonable to believe over time and generations, humans may develop an extra or altered digit on the hand to accommodate cell phone usage.</span>
Doing this for the points LOL
