Bacillus thuringiensis, a bacterium commonly known as Bt, produces a protein that can killcertain insects that feed on corn crops. Scientists have been successful in transferring the genethat codes for this protein from the bacterium tothe corn, so the corn can now make the Btprotein. Corn borers, insects that eat corn, diewhen they feed on corn containing the Btprotein. A potential problem associated withincreased production of Bt corn is:
(1) corn borers may stop feeding on corn plants
(2) corn borers may develop resistance to the Btprotein
(3) farmers may need to use less pesticide tocontrol corn borers
(4) corn borers may compete with other insectsthat feed on corn plants
