Answer 1

proteins.  

Answer 2

Spider silk is composed mainly of complex protein molecules.  It is a sequence of amino acids (usually alternating glycine and alanine, or alanine alone) that self-assemble into a beta sheet conformation.  Besides proteins, there are also pyrrolidine, potassium hydrogen phosphate, and potassium nitrate.

Different types of spiders have slightly different silk.

The elements in proteins are carbon, oxygen, hydrogen, and nitrogen.
