1.
| | One of the safety controls that is unique to plant incorporated protectants is that: |
|
| | A) | They don’t have to be monitored by any agency because there is no need for pesticides to be used any longer. |
| | B) | They are in the watchful care of the USDA, FDA and EPA combined. |
| | C) | They only have to be monitored at harvest time rather than throughout the growth cycle of the plant. |
| | D) | There ability to resist insect pest attacks makes them more prone to fungus invasion. |
|
2.
| | Why was the Environmental Protection Agency already familiar with the use of Bt toxin? |
|
| | A) | They had read about preliminary research that had been done in controlled lab settings with Bt toxin. |
| | B) | They had already made use of it in rice and barley pesticide resistance. |
| | C) | Bt toxin has been used safely as an external pesticide for many years. |
| | D) | Bt toxin had already been used for human plastic surgery use for several years. |
|
3.
| | What is one major area of concern about the use of genetically induced Bt toxin production? |
|
| | A) | The toxin will be made continuously, so will the insects become resistant to it by evolutionary selection pressures? |
| | B) | The danger that it will alter the safety for human consumption. |
| | C) | The risk that the plant will have growth with no limiting factor. |
| | D) | The danger in how the Bt toxin is prepared in a laboratory. |
|
4.
| | What is the potential risk of Bt toxin use in corn crops to Monarch butterfly populations? |
|
| | A) | The toxin will accumulate on their wings and hinder flight. |
| | B) | The toxin will prevent eggs from hatching. |
| | C) | The toxin will alter their migratory signals. |
| | D) | The toxin will be consumed in great quantities by erupted caterpillars. |
|
5.
| | What are non-Bt refuges? |
|
| | A) | They are plants that do not produce the toxin and are planted with the toxin producing ones to serve as non-resistant pest refuges. |
| | B) | They are plants that for some reason don’t synthesize the Bt toxin. |
| | C) | They are plants that stop producing the toxin over time. |
| | D) | They are plants that help to draw pests to the area to be killed by the toxin producing plants. |
