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

DNA, the proteins in hair, rubber car tires.  

Step-by-step explanation:

Polymers are large molecules consisting of long chains of small repeating units.

DNA is a natural polymer that consists of hundreds of millions of repeating units called nucleotides.

Hair protein consists of long chains of amino acid repeating units.

The rubber in car tires is a mixture of natural and synthetic rubber. Natural rubber consists of long chains of isoprene repeating units. In one type of synthetic rubber, the repeating units are butadiene and styrene molecules.

The glass in a bottle is not an organic polymer. However, some chemists consider it to be a highly cross-linked inorganic polymer of SiO₂.

Ice crystals are not even inorganic polymers, because the water molecules are held together only by hydrogen bonds, not covalent bonds.
