Answer:
Yes , when viruses infect us, they can embed small chunks of their genetic material in our DNA. Although infrequent, the incorporation of this material into the human genome has been occurring for millions of years. As a result of this ongoing process, viral genetic material comprises nearly 10 percent of the modern human genome. Over time, the vast majority of viral invaders populating our genome have mutated to the point that they no longer lead to active infections. But, as scientists funded by the National Institutes of Health have demonstrated, they are not entirely dormant.

Answer:
Stabilizing selection is occurring because the average is favored.
Explanation:
There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
Balancing selection, also called Stabilizing selection, eliminates individual with extreme traits and favors individual that exhibit medium-range characteristics, that gets to survive.
In the exposed example, babies with very low or very high birth weight have fewer possibilities to survive. Stabilizing selection eliminates individuals with extreme weight and favors individuals that exhibit medium weight, which are the ones that get to survive.
<span>The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.</span>
Answer:
I think the answer is A. They are different species, therefore their niches do not overlap and they do not compete.
