Question

why is genetically engineered silk better than nylon?
○ it is biodegradable.
○ it is renewable.
○ it is sturdy.
○ it is elastic and flexible.
○ it is biodegradable and renewable.

Explanation:

Genetically engineered silk, derived from biological sources, is biodegradable (breaks down naturally) and renewable (can be produced repeatedly from living organisms). Nylon is a synthetic polymer derived from non-renewable fossil fuels and is non-biodegradable. While silk may have other properties like sturdiness or elasticity, the key advantages making it "better" than nylon relate to environmental sustainability, which combines biodegradability and renewability.

Answer:

It is biodegradable and renewable.
