1. A spiderweb and a Kevlar jacket have some obvious differences. Which property is similar between the web and the jacket?
- surface area
- thickness, expressed as a number of atoms
- overall strength
- arrangement of atoms in molecules
2. Assuming silk from spiderwebs could be made just as strong as Kevlar, why would a company still choose to use Kevlar in producing bulletproof fabrics?
- A much larger amount of silk might be needed to produce the same effect.
- Spiderweb silk would likely be rejected by the body.
- The cost might be higher for producing spiderweb silk.
- Spiderweb silk likely involves more chemicals.
3. Which microscopic detail affects the strength of different forms of silk?
- Different silk strands are made with different types of atoms.
- Different types of silk are in long strands or in other very different arrangements.
- Different silk strands have different combinations of amino acids.
- Different types of silk do not have the same strength if they come from different sources.
4. Which type silk is the strongest?
- nonbiodegradable
- minor ampullate
- major ampullate
- biodegradable
5. Which natural source has been bioengineered to make silk proteins?
- mulberry leaves
- goat milk
- goat hair
- mulberry bark

Different sources of fibres

There are different sources of fibres which can be genetically engineered for living organisms like the spider.

The fibre silk gotten from spiders are known to be the strongest, toughest materials on the Earth. But recently, engineers has designed amyloid silk hybrid proteins and produced them in engineered bacteria.

Even though these synthetically produced fibres are stronger than Kevlar, they prefer to use Kevlar because a much larger amount of silk might be needed to produce the same effect.
