The vascular bundles in monocot stems are: MCQ with Answer and Explanation

Explanation:
Binary fission is the primary and most common method of asexual reproduction in bacteria. In this process, the bacterial cell replicates its DNA and then divides into two identical daughter cells. Under optimal conditions, some bacteria can divide every 20 minutes. Bacteria can also exchange genetic material through processes like conjugation, transformation, and transduction.

Explanation:
Bt cotton is a transgenic crop developed by inserting cry genes (e.g., cryIAc, cryIIAb) from the soil bacterium Bacillus thuringiensis (Bt). These genes code for crystal proteins (Cry proteins) that are toxic to certain insect pests, particularly the cotton bollworm. When the insect ingests the protein, it is activated in its alkaline gut, creating pores in the gut lining, leading to the insect's death.

Explanation:
Carolus Linnaeus, a Swedish botanist, formalized the system of binomial nomenclature for naming organisms. Louis Pasteur made immense contributions to microbiology, including the development of the first effective vaccine against rabies. Gregor Mendel is the father of genetics, known for his laws of inheritance; the structure of DNA was discovered by Watson and Crick. Thus, statements 1 and 2 are correct.
