Question

Scientists have taken genes from a species of bacteria that is pathogenic to several insects and inserted the genes into potato plants. The bacterial genes cause a cell to produce toxins that kill the insects. As the potato plants grow, every cell of the plant contains the toxin-producing genes. This makes the potato resistant to attack by crop pests. Which of the following is a limitation of this new technology? A. There are no foreseen limitations with inserting bacterial genes into crop plants. B. The introduced gene will cause more diversity in the potato's genome, thus causing the potato plant to become extinct. C. The genetically altered potato plants will kill off so many insects that companies that manufacture pesticides will soon go out of business. D. Over time, insects are likely to develop resistance to the bacterial toxin. Reset Next

Answer 2

Answer: D. Over time, insects are likely to develop resistance to the bacterial toxin.

Step-by-step explanation:

Insects have been known to develop a resistance to pesticides and this toxin in all probability will not be different. Insects thrive on feeding on crops and so will evolve to be able to do so as much as possible.

This will happen when some of the insects develop a resistance to the toxins and the ones that do not will die leaving only the immune ones. These immune ones will now be the ones to reproduce and as they pass that immunity to their offspring, the species will keep getting more resistant to the toxin until overtime, all of the insects will have immunity.
