Answer and Explanation:
Image result for How did the results prove the semiconservative model of DNA
The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. Although Meselson and Stahl did their experiments in the bacterium E.
According to scientists, many years ago their was a supercontinent called "Pangaea." As years went by, the continents slowly drifted apart which is what's today. However, from recent discovers, scientists predict that in about 250 millions years from now the continents will merge again, however this time, in a different order ("Pangaea Ultima"). So the answer to your question is D.

Answer:
IgM, IgA, IgE, IgD and IgG
Explanation:
IgM functions in the initial response to offence.
IgA is important for protection of mucus membranes such as in saliva, sweat, tears and gastric fluid.
IgE is active during allergic reactions and defense against infections.
IgD is found on the surface of lymphocytes and is activated upon contact with antigens.
IgG forms part of the secondary response to antigen and is also responsible for newborn protection.
single-nucleotide polymorphism, I think this might be it. I hope it helps.
