What did Jeffrey Turner discover about using Nubian goats for possible silk production?

• Nubian goats already make a similar substance

• Nubian goats have high amounts of protein in their milk

• Nubian goats and spiders both prefer living in large groups

• Nubian goats and spiders have body parts that are similar

In the process described in lines 35 through 47, which step allows the threads to become strong enough for surgical procedures.

• The silk proteins are turned into clumps

• The silk is stretched repeatedly

• Salt is added to the goat's milk

• Water is added to thin the clumps
