Answer 1

Answer:

I guess Option C is true

Answer 2

A.  Polymers are substances that have relatively large molecules.

Explanation:

• A polymer is a chemical substance bound in long repeated chains of molecules.
• Long chains of repeated molecules with unique properties depending on their type of bonds are called polymers.
• They are stretchable like rubber.
• Polymers are can be natural or man made.
• The most abundant polymer is cellulose which is an organic compound which is found in the plant's cell wall.
• Polymers have unique properties due to their structure that can be adapted for different uses.
• Examples: Silk, cotton, DNA, cellulose, rubber and proteins.
