Question

hydrocarbons: form the basis for most macromolecules. increase the h+ in a solution. are held together by ionic bonds. all of the above. readily interact with water.

Explanation:

Hydrocarbons are organic compounds consisting of only carbon and hydrogen atoms. Macromolecules like carbohydrates, lipids, proteins, and nucleic acids (which are the basis of life) have carbon - based skeletons. Hydrocarbons are non - polar and do not increase \( [H^+] \) (acids increase \( [H^+] \)), they are held together by covalent bonds (not ionic bonds as ionic bonds are between ions of opposite charges), and they are hydrophobic (do not interact readily with water).

Answer:

form the basis for most macromolecules.
