<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.

I think the EPA adminsters the act.....and one benefit is that harmful chemicals that are released into the air are monitored and only a certain amount is able to be released without the company being fined.
Nitrogen must be converted into nitrates before organisms can use it. If soil lacks nitrogen fixing bacteria, then it has few nitrates for the plants to take in.
<span>Atomic mass=Total number of protons + Total Number of neutrons.
Here
Total number of protons=8
Total number of neutrons=9
Atomic mass= 8 + 9
= 17
Answer is 17.</span>
Weight= Mass x Force of gravity
In this case weight= 5 x 5.7 = 28.5
