Answer:
The process of making a copy of gene is called DNA replication.
Explanation:
This is a four step process. In first step, the DNA molecule which is double helical structure is unzip. This is carried out by enzyme called helicase which is also called biological scissors. Then after that DNA form Y like structure having complementary base pairs. Two strands are formed ; leading strand and lagging strands. They complementary base pairs allow the formation of new strands with help of primer. So new strand is then a copy of gene or called replicated strand.
Darwin called the ability of an organism to survive and reproduce in its environment fitness.
Some organisms were fit to do all of these things, whereas others were not.
a because the marble changed its position quickly meaning that it was in motion
In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender
They bond together creating compounds
