Verified step by step guidance

Identify the chemical composition of each biomolecule type listed in the options: Nucleic acids, Carbohydrates, Steroids, and Fatty acids.

Recall that nucleic acids (DNA and RNA) are composed of nucleotides, which include a nitrogenous base, a phosphate group, and a sugar molecule. This means nucleic acids contain both nitrogen and phosphate.

Understand that carbohydrates are primarily composed of carbon, hydrogen, and oxygen, and do not typically contain nitrogen or phosphate.

Recognize that steroids are lipids characterized by a four-ring structure made of carbon and hydrogen, and they do not contain nitrogen or phosphate.

Note that fatty acids are long hydrocarbon chains with a carboxylic acid group, primarily composed of carbon, hydrogen, and oxygen, and do not contain nitrogen or phosphate.
