Is there a list to chose from or are you just looking for them all
Answer:I think they would die from not doing anything.
A double helix is <span>a pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule. or in other words a double spiral.</span>
Unify means to make or become united uniform, or whole.
(I personally don't agree that evolution is true; but here is my answer)
Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.
I hope this helped you!
<u>Answer</u>: option B they have a random gene mutation that affects their fur colour.
<u>Explanation</u> :-
- <em>Variation</em> is the phenomena which occurs in all populations.
- These variations result in slight differences in the phenotypes of individuals .
- These variations only arise due to <em>random mutations </em>that arise in the individuals’ genome and then can be inherited by their offspring.
- There is always a probability of one particular trait to make the individuals survive better in the environment as compared to other trait.
- The individuals having the trait that helps them to survive better in the environment tend to survive more and leave more progeny. This is termed as <em>survival of the fittest</em>.
- Thus, according to the question it can be inferred that the dark fur colour arose due to a <em>random mutation </em>since it is the only source of variation. Since, in the given environmental conditions the mice having the dark fur colour were less susceptible to the predators they are better fitted to survive.
- The dark brown fur coat mice, survive better, leave more progeny and hence, increase their population with time. However, the orginal source of origin of this trait was a random mutation. Had this mutation not occured, the dark coloured fur mice would not have been there.
So, a <em>random gene mutation affecting the fur colour made the dark coloured mice first appear in the population.</em>
