Answer 2

Silk is a naturally occurring polymer that comes from a variety of bug and spider species.

Explanation:

• It is made up of two proteins, sericin and fibroin, the latter of which is an FDA-approved material for medical devices.
• The major component of natural silk is fibroin. It's a form of protein that can't be dissolved in water.
• It has an amino acid sequence. Amino acids are linked together via the creation of amide bonds. As a result, silk is a polyamide.
• Natural polymer:

Natural polymers can be obtained from the environment(nature). Water is usually used in their construction.

Examples

• Silk
• wool
• DNA
• cellulose
• proteins

Final answer:

Silk is a high-performance material with toughness and strength that rivals those of man-made polymers.
