A copper pan is made by a person. Is the pan synthetic?(1 point)
Responses
No, it is not synthetic because copper is an element found in nature.
No, it is not synthetic because copper is an element found in nature.
No, it is not synthetic because copper is not recyclable.
No, it is not synthetic because copper is not recyclable.
Yes, it is synthetic because people make synthetic materials.
Yes, it is synthetic because people make synthetic materials.
Yes, it is synthetic because copper needs to be physically separated from other elements.

No, it is not synthetic because copper is an element found in nature.
A polymer is a chain of repeating compounds found in both natural and synthetic materials.
The correct answer is:
a chain of repeating compounds found in both natural and synthetic materials
To explain how to get this answer:
To understand what a polymer is, we can break down the options and eliminate the incorrect ones.
1. "A piece of a natural resource that has been broken down before it is recycled into new materials." This option describes the process of recycling, but it does not define what a polymer is.
2. "A natural resource used to make synthetic materials." While natural resources are indeed used to make synthetic materials, this option does not specifically refer to a polymer.
3. "A chain of repeating compounds found in both natural and synthetic materials." This option correctly defines a polymer as a chain of repeating compounds that can be found in both natural and synthetic materials. This definition accurately describes the nature of polymers.
4. "A natural resource formed on Earth from plant or animal remains." This option describes a natural resource but does not specifically define a polymer.
By eliminating the incorrect options, we can conclude that the third option, "a chain of repeating compounds found in both natural and synthetic materials," is the correct answer.
