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.

Polymers are made up of made of repeating subunits.

Polymers are defined to be substances built from similar units bonded together.

Polymers can be synthetic or natural.

Option (d) is the correct answer.

Explanation:

A basic unit of a polymer is called a monomer. And when number of monomer units combine together then it results in the formation of a polymer.

As poly means "many" and mer means "units". So when many units combine together then they form a polymer. These units are repetitive in nature.

Thus, we can conclude that it can be known about all four polymers, despite their differences that they are made of repeating sub-units.
