List the big four macromolecules of life.

Multiple Choice

Carbon is considered the building block of life because

• It bonds easily with oxygen only.

• It has the ability to form complex stable molecules.

• It has the unique ability to bond with hydrogen only.

• It easily bonds with elements to form unstable compounds.

Multiple Choice

An amino acid is considered a monomer for making proteins. This means

• a monomer is the building block for proteins.

• a monomer is the building block for carbohydrates.

• a monomer is an example of a polymer.

• a monomer is larger than a protein.

Multiple Choice

A polymer is formed when

• elements like carbon and hydrogen combine.

• Oxygen combines with nitrogen.

• Monomers combine to former large molecules.

• Large molecules are broken down into small molecules.
