Question

synthetic materials, natural resources quick check
what is a polymer? (1 point)
○ a natural resource used to make synthetic materials
○ a natural resource formed on earth from plant or animal remains
○ a chain of repeating compounds found in both natural and synthetic materials
○ a piece of a natural resource that has been broken down before it is recycled into new materials

Explanation:

A polymer is defined as a large molecule composed of many repeating subunits (monomers). This structure can be found in both natural (e.g., DNA, cellulose) and synthetic materials (e.g., polyethylene).

• The first option is incorrect as it refers to a raw material source rather than the polymer itself.
• The second option describes fossil fuels (a type of natural resource from plant/animal remains), not polymers.
• The fourth option describes a processed fragment of a natural resource, not a polymer's molecular structure.

Answer:

C. a chain of repeating compounds found in both natural and synthetic materials
