Ans. (A). Proteins expressing color in butterfly wings mutate to improve camouflaging abilities of butterflies.

Adaptation is described as permanent change in organism due to mutation that leads to better survival of that organism.

Camouflage helps the butterfly to hide in its surrounding environment to avoid predators. So, if a mutation leads to expression of protein in butterfly's wings that improve camouflage in butterfly will show an adaptation as would lead to increased survival of that butterfly population.

Thus, the correct answer is option (A).

A child was exposed to a disease-causing virus (most likely chicken pox from the Varicella zoster virus) when he was 5 years old

STatiana [176]

Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.

Explanation:

When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through antibodies. Once it does it will keep a memory of it that it can use if this virus enters the body again. This will be done through the secondary immune system.

As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.

Thanks to its memory cells, the virus will remain much less time in the body.

Approximately 60% of human genes are also found in fruit flies. About 97.5% of human genes are also found in mice. What does thi

This evidence suggest that all three living creatures that are mentioned have a common ancestor, even though they have been split into different types of groups of living organism millions of years ago.

Science suggests that all of the living organisms on the planet have a common ancestor. Since we are talking about a common ancestor that lived few hundred million years ago, the living organisms split into different groups, and they do not resemble each other nowadays. The fruit fly is an insect, and the humans and mice are mammals, so they are into totally different groups, and it is easy to see by the genetic evidence that they are very distantly related, but the humans and mice are much more closely related because they belong to the same super family, and their connection is much more recent.

How are amino acids assembled during translation?

TRNA reads codons from mRNA and then brings attached amino acids accordingly. Amino acids are connected in long chains called proteins.
