In the united states today, about half of the corn crop is genetically engineered with a protein that is toxic to corn borers, an insect pest of corn. which of the following conditions would be necessary for evolution of resistance to the toxic protein to occur in the corn borer?
a. the corn borer must have or generate (by mutation) heritable variation in resistance to the toxic protein.
b. the resistant corn borers must survive better or reproduce more than non-resistant corn borers.
c. the corn borers must experience unlimited success in their ability to survive or reproduce.
d. the corn borers must experience no success in their ability to survive or reproduce.
e. the corn borer must lack variation in resistance to the toxic protein.

Protein and polypeptide sequences can be determined by first partially hydrolyzing the protein or polypeptide followed by amino acid sequencing of the fragment pieces using the chemical degradation process known as edman degradation. determine the sequence of the initial (18-amino acid) polypeptide that produces the following five partial sequences after hydrolysis and edman degradation.
