4. Bacillus thuringiensis (Bt) is a bacterium that contains a gene that results in the production of a natural pesticide that kills insects. Genetic engineers have successfully inserted this Bt gene into the DNA of some corn varieties, allowing the corn to produce its own pesticide.
What negative consequence could result from this technology?
A. Only corn that is resistant to the Bt gene will survive.
B. Individual insects that eat the genetically modified
corn will develop resistance to Bt.
C. The genetically modified crops will insert this Bt gene
into the DNA of humans that eat the corn.
D. Only Bt resistant insects will survive to reproduce,
eventually producing a population of entirely resistant
individuals.
