Which substances are made up of polymers? DNA
a glass bottle
ice crystals
the proteins in hair
rubber car tires

Explanation:

The following are polymers

DNA : it is a polymer of nucleic acids

Protein in hair: it is a polymer of amino acids

rubber car tires: it is a polymer (it can be nylon or buna rubber etc)

ICE crystals : it is not a polymer,It is just a compound (water) in its solid phase

All these are made up of polymers.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
