Question

question 1 (1 point)
what do silk, dna, nylon, cellulose, and styrofoam all have in common?
they are all polymers.
they are all carcinogens.
they are all natural substances.
they are all monomers.

Explanation:

• Polymers: Silk (protein polymer), DNA (nucleic acid polymer), nylon (synthetic polymer), cellulose (carbohydrate polymer), styrofoam (polystyrene, a synthetic polymer). All are made of repeating units (monomers).
• Carcinogens: No evidence all these are carcinogens.
• Natural substances: Nylon and styrofoam are synthetic.
• Monomers: They are made of monomers, but themselves are polymers.

Answer:

They are all polymers.
