The following is part of a newspaper article about a new variety of corn:
bug-free corn farmers lose a lot of their crops to insect pests each year. they have to spray their crops with insecticide to kill the insect pests. now, scientists have developed a new variety of corn called bt corn that contains its own insecticide. some kinds of bacteria make a natural insecticide called bt. the scientists have taken the gene for this insecticide from the bacteria and inserted it into corn plants.

a. use the information from the newspaper article to suggest how the addition of this gene could increase the farmer’s corn crop.

b. the development of bt corn is one example of genetic engineering. explain the meaning of the term “genetic engineering.”

c. state two other examples of genetic engineering.
