This chart lists four kinds of polymers and their sources. A 2-column table titled polymer examples. The first column labeled name of polymer has entries D N A, cellulose, nylon, hair. The second column titled source of polymer has entries inside of cells, plant material, synthetic material, animal material.

What can be known about all four polymers, despite their differences?

They come from living things.
They share ionic carbon bonds.
They are at least 100 monomers long.
They are made of repeating subunits.

D. They are made of repeating subunits.

Explanation:

The first column represting polymers such as DNA, cellulose, nylon, hair are labelled with cells, plant material, synthetic material, animal material and They are made of repeating subunits.

Not all the entries in the first column come from living things as nylon comes from synthetic material (man-made). But all four (DNA, cellulose, nylon, hair) are conists of repeating unit.

DNA made up of nucleotides, cellulose is made up of rpeating units of monomer glucose, nylone is made of repeating unit of two monomers  hexamethylene diamine and adipic acid, and hair is made of repeating unit of  protein called keratin.

Hence, the correct answer is "D. They are made of repeating subunits."
