Answer:
The bond between the _second_________ phosphate group and the third__phosphate group is a high energy bond.
Explanation:
Adenosine triphosphate is a nucleotide with three phosphate groups. The second and third phosphate groups are bonded by high energy covalent bonds to the rest of the ATP molecule, which consists of a sugar, which is ribose, the first phosphate group, and the nitrogenous base which is adenine. All of the phosphate groups are negatively charged and repel each other, so a high energy covalent bond is necessary to attach these phosphate groups together and keep the forces from pulling them apart.

Answer - D. (The genetic code)
The genetic code is the nucleotide base sequence on DNA (with which information is encoded within genetic material). The nucleotide base sequence<span> codes for a sequence of amino acids, which are in turn used by living cells as the basic building blocks of proteins.</span>
