Answer:
A) The two strands of a DNA molecule are parallel and complementary.
Explanation:
DNA is a polymer of nucleotide and this nucleotide are made up of a deoxyribose sugar molecule, a nitrogenous base, and a phosphate group. In DNA genetic information of the cell is stored in the form of nitrogenous bases.
DNA is double-stranded and both the strands run anti-parallel with each other. This anti-parallel orientation provides the nitrogenous base of one strand to form hydrogen bonds with the nitrogenous base present on the opposite strand.
In DNA adenine base pairs with thymine with two hydrogen bonds and guanine base pairs with cytosine with three hydrogen bonds. So the false statement is A.
Answer:
You take any of the "signs of change in populations of organisms and their environments". For imagine, Australopithecus (early man) turning to Homo sapiens. In that way they could tell that you took this journey.
