Question

select all the correct answers. which substances are made up of polymers? dna a glass bottle ice crystals the proteins in hair rubber car tires

Explanation:

To determine which substances are made of polymers, we analyze each:

• DNA: Is a nucleic acid polymer (nucleotides as monomers).
• a glass bottle: Glass is an inorganic solid (not a polymer).
• ice crystals: Water (H₂O) in crystalline form (not a polymer).
• the proteins in hair: Proteins are polymers (amino acids as monomers).
• rubber car tires: Rubber is a polymer (e.g., polyisoprene).

Answer:

• DNA
• the proteins in hair
• rubber car tires
