Proteins

Explanation:

Amino acid is a monomer. It is the building block of the polymer protein. Amino acids join to one another through peptide linkages to form a polypeptide. Polypeptides combine with each other in a 3D conformation to form proteins. There are 20 different amino acids in the cell. Amino acids have different side chains which make them acidic, basic, neutral, polar or non-polar.

step-by-step explanation:

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
