Prickly pear cacti were introduced into Queensland, Australia as ornamental plants, starting in 1788. They quickly spread to cover over 25 million hectares of Australia by 1920, increasing by 1 million hectares per year. Digging, burning, and crushing all proved ineffective. The biocontrol agent used to control it was:
1. | Cactoblastis cactorum | 2. | Trichogramma minutum |
3. | Nematus ribesii | 4. | Icerya purchase |

II: | Only first heart attacks can be treated with a thrombolytic. |
1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct and II is incorrect.
4. Both I and II are incorrect.

Statins act by selectively inhibiting:
1. | HMG CoA synthase | 2. | HMG CoA reductase |
3. | Thiolase | 4. | Mevalonate kinase |
Consider the given two statements:
I: | If biogas is smelled anywhere windows and doors should be opened immediately. |
II: | The content of toxic hydrogen sulfide has been responsible for serious accidents. |
1. Both I and II are correct and II explains I.

2. | hydrolysis → acetogenesis → acidogenesis → methanogenesis. |
3. | acetogenesis → acidogenesis → hydrolysis → methanogenesis. |
4. | acetogenesis → acidogenesis → methanogenesis → hydrolysis |
