Biology Homework 2.2

Suppose you are going to draw models of the four main biomolecules. Which statement describes how the models will be similar?

• They will all be formed around carbon chains and rings.

• They will all include a chain of amino acids.

• They will all have hydrocarbon chains connected only by double bonds.

• They will all include a sugar, a phosphate group, and a base.

Which of these evidence statements should you include in an explanation of the relationship between carbon, amino acids, and proteins? Select all correct answers.

• Amino acids are polymers made up of proteins.

• Proteins are polymers made up of amino acids.

• Proteins and amino acids are polymers, because they contain multiple carbon atoms.

• Amino acids are monomers made up mostly of carbon, hydrogen, nitrogen, and oxygen.

Complete the statements by selecting the correct terms.
