The correct option is **cotton**. It is a natural material and not a fossil fuel, whereas vinyl, petroleum, and natural gas are all fossil fuels or synthetic materials derived from fossil fuels.
Answered by GPT-4o mini
The correct response is **It needs to go through a chemical reaction.** For a natural resource to be transformed into a synthetic material, it typically undergoes chemical processes that alter its composition or properties.
Answered by GPT-4o mini
The correct response is **a chain of repeating compounds found in both natural and synthetic materials.** Polymers are large molecules made up of repeating structural units (monomers), and they can be found in both natural substances like rubber and silk, as well as synthetic materials like plastics.
Answered by GPT-4o mini
The correct response is **Oil and natural gas are chemically broken down into small compounds that combine to form plastic.** This process involves cracking and polymerization, where smaller molecules (monomers) are chemically joined to form long chains (polymers) that constitute plastic.
