Question

Example of polymeric substance in biology

Answer 1

Answer:

A polymer is a large molecule that is made up of repeating subunits connected to each other by chemical bonds.

While plastics are used as a common example of polymers, there are many other materials which are also polymers. Polymers include:

Anything plastic

Proteins, such as hair, nails, tortoise shell

Cellulose in paper and trees

DNA

Silly putty

Slime

Rubber

So while paper plates, styrofoam cups, plastic bottles, and a block of wood are all examples of polymers, there are some materials which are not polymers. Examples of materials which are not polymers include:

Elements

Metals

Ionic compounds, such as salt

Usually, these materials form chemical bonds, but not the long chains that characterize polymers. There are exceptions. For example, graphene is a polymer made up of long carbon chains.
