Which of the following insecticide is obtained from the roots of Den-is elleptica?
1 Cinerin
2 Nicotine
3 Rotenone
4 Pyrethrum
Explanation:
Exp: A chemical compound known as Retenoids are found in several plants such as Elleptica, Jicama vine plant and in the roots of several fabaceae family members. Rotenone compound used as broad spectrum insecticide and pesticide. It is colourless, odourless, crystalline ketonic chemical compound. - Cinerin also contain insecticidal properties but it is obtained from Pyrethrum flower.

Hydroponics is the method of
1 Water conservation
2 Plant development in water without soil
3 Plant development without soil
4 Plant development in saline soil
Explanation:
Exp: In hydroponics method plants developed in water without soil, using a nutrient - rich water solution. - The advantages of hydroponics method to faster growth rates of crops, less susceptible to pests and diseases than soil based system etc.

Insect resistance transgenic cotton has been produced by inserting a piece of DNA from
1 an insect
2 a bacterium
3 a wild relative of cotton
4 a virus
Explanation:
Exp: Insect resistance transgenic cotton has been produced by inserting a piece of DNA from a bacterium Bacillus thuringiensis (Bt). - Bt cotton has been genetically modified by the insertion of one or more genes from a common soil bacterium, - Bacillus thuringiensis. These genes encode for the production of insecticidal proteins, thus transformed plants produce one or more toxins as they grow. The genes that have been inserted into cotton produce toxins that one limited in activity almost exclusively to caterpillar pests (Lepidoptera).
