Observe the given figure and name the following rays : (i) ray AB (ii) ray BC (iii) ray CD

Which of the following is /are cellulose (i) Paper " " (ii) Cotton fibre (iii) Chitin " " (iv) Glycogen

Read the following and answer questions from Q.1. to Q.5. given below: Plants having foreign genes in their genome through genetic engineering are called transgenic plants. Genes can be incorporated either through a vector or through direct introduction of DNA. Bt cotton is a genetically modified organism which is pestresistant. It contains gene cry I Ac and cry II Ab of Bacillus thuringiensis. It is used to control lepidopterans, coleopterans and dipterans. Bt cotton can resist cotton bollworm and produce higher yields. Cry gene produces cry protein or Bt toxin. It is an endotoxin which remains as protoxin in plants and converted to active toxin after getting ingested by the insects. Alkaline pH of the insect gut solubilizes the protein crystals, the activated toxin creates pores to the mid guts wall of theinsects which cause them to death. Cotton bollworms are killed by the protein encoded by the gene
