<h3>How are gene variants involved in evolution?</h3>
Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from genetic variations (also called mutations) or from a normal process in which genetic material is rearranged as the cell is about to divide (known as genetic recombination).
Genetic variations that alter gene activity or protein function can introduce different traits into an organism. If a trait is beneficial and helps the individual survive and reproduce, the genetic variation is more likely to be passed on to the next generation (a process known as natural selection).
Over time, as generations of individuals with the trait continue to reproduce, the favorable trait becomes more and more common in a population, making that population different from the ancestral population. Sometimes the population becomes so distinct that it is considered a new species.

Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
<em>Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.</em>
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.
The biodiversity on Earth indicates that the organisms cannot tolerate extreme environments. Therefore, D. is the correct answer.
5 chromosomes. Meiosis results in 4 haploid cells, meaning they have "n" pairs of chromosomes. The diploid cell that the 10 chromosomes originated in has "2n" pairs. This leaves us with a simple equation to solve the problem, 2n=10, so n must equal 5 chromosomes.
