Answer 1

CONCEPT:

Natural Polymers

Natural polymers are polymers that occur naturally in living organisms or in nature. They are formed by biological processes.
Examples of natural polymers include:
- RNA: A nucleic acid that plays a role in protein synthesis and is made of nucleotide monomers.
- Cellulose: A polysaccharide found in the cell walls of plants, composed of glucose monomers.
- Starch: A storage polysaccharide found in plants, also composed of glucose monomers.
These polymers are produced naturally and are essential for biological processes.

EXPLANATION

Rayon is a synthetic polymer, not a natural polymer. It is derived from cellulose but undergoes chemical processing to create a fiber used in textiles.
Although rayon originates from natural cellulose, the extensive chemical modification during its production makes it a synthetic polymer.
On the other hand:
- RNA is a natural polymer as it is formed in living organisms.
- Cellulose and starch are also natural polymers because they are produced by plants through biological processes.

Therefore, the correct answer is Rayon.
