question 4(multiple choice worth 4 points)
(06.01 mc)

what is the likely advantage of growing a genetically modified variety of corn that possesses its own pesticide?

• the shelf life and sale of corn would increase.
• it is more efficient and economical to grow this variety.
• when consumed it offers more nutrients than the regular variety.
• when consumed it improves the quality of life of people with genetic disorders.

Analyze the biological mechanism

Using the Genetic Engineering knowledge point
Genetically modified (GM) crops, such as Bt corn, are engineered to produce their own insecticidal proteins (pesticides). This internal defense mechanism directly targets specific pests that feed on the crop, reducing or eliminating the need for farmers to purchase and apply chemical pesticides externally.

Evaluate the economic and operational impacts

Using the Genetic Engineering knowledge point
By reducing the reliance on external chemical pesticide applications, farmers save money on chemical purchases, fuel, and labor. Additionally, preventing pest damage directly protects crop yields, making the cultivation process more efficient and economical.

Assess the alternative options

Using the Genetic Engineering knowledge point

• Shelf life and sales: Producing a pesticide does not inherently extend shelf life (which is related to ripening or spoilage genes).
• Nutritional content: Pesticide production does not increase the nutrient profile of the corn.
• Genetic disorders: Consuming pest-resistant corn does not treat human genetic disorders.
