Q: What makes organic compounds ubiquitous is the chemistry of their what? Read this paragraph and choose the correct option from the provided answers: The Chemistry of Carbon What makes organic compounds ubiquitous is the chemistry of their carbon core. Recall that carbon atoms have four electrons in their valence shell, and that the octet rule dictates that atoms tend to react in such a way as to complete their valence shell with eight electrons. Carbon atoms do not complete their valence shells by donating or accepting four electrons. Instead, they readily share electrons via covalent bonds. Choices: - carbon shell - dioxide shell - dioxide core - carbon core A:
(A).
carbon core

Read this paragraph and choose the correct option from the provided answers: The only difference between each nucleotide is the identity of the base. There are only four possible bases that make up each DNA nucleotide: adenine (A), guanine (G), thymine (T), and cytosine (C). Choices: - taurine - phenylalanine - guarine - cytosine A:
(A).
cytosine
