Answer:
50% wild type and 50% black i.e. 1:1 phenotypic ratio
Explanation:
Given, b+ = wild type allele
b = recessive allele
b+b+ = dominant wild type
b+b = heterozygous wild type
bb = recessive black
First cross: female b+b (wild type) X male bb (black) = bb, bb, b+b, b+b
Since bb and b+b are in 1:1 phenotypic ratio, 52 black and 58 wild type progeny are produced.
From this progeny second cross occurs between:
female bb (black) X male (wild type) b+b = bb, bb, b+b, b+b
Again the same 1:1 phenotypic ratio is obtained. Half of the progeny will be be black (bb), other half will be wild type (b+b).
Answer:
The correct option is <em>B) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.</em>
Explanation:
Organism of a population might have genetic variations in them due to many reasons. The species of a population which are better adapted to live in a particular area are able to survive and produce more offsprings. As a result, that particular area increases in that genetic variant.
In the above scenario, some of the wolves had variants in their digestion which made them better adapted to live with the humans as they could eat wheat, rice etc. The wolves which did not have variants in their digestion couldn't survive in the human areas.

Answer:
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
The correct answer to this open question is the following.
The inevitable result of the commercialization of reproduction, which is governed by contract and the purchase of body parts and functions is that unfortunately, a "business of the body" has been created, many times in an irresponsibly way.
This has opened an ethical debate about the sacrality of the human body or if it is a simple or another way to do business as if you were selling auto parts, furniture, or tools.
And then, here comes religion and its point of view and perspectives. Many Americans do not agree with the idea of having a business with the human body. Most of these people think that the human body is sacred and deserves sacred treatment, not an industrial one.
So the debate in the United States society goes on, and for some, it is a new business; a very profitable one. For others, is a questionable practice that has to be regulated.
