Study the following statements regarding Bt toxins produced by bacterium Bacillus thuringiens is and select the correct one
Some strains of Bacillus thuringiens is produce proteins that kill certain insects such as lepidopterans, coleopterans and dipterans
Bt toxin proteins do not kill the bacteria themselves because the toxin proteins occur in an inactive form called protoxins
When an insect ingests the inactive Bt toxin, it is converted to an active form of toxin due to alkaline pH of the gut which solubilises the protein toxin crystals
