Answer:
Answer is B, habitat isolation.
Explanation:
Habitat isolation can simply be explained as a situation whereby two insects or organisms of the same species, that have the ability to meet and reproduce could not, because they are living in different habitats.
These different habitats might even be in the same geographical location or area. That is, one insect might be living in or on the surface of the water, and the other living in the soil or the tree. Due to this effect, the insects are unlikely to meet and reproduce.
D - birth control is the most widely accepted method
One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.
