Answer: Option B
Solution (By JKExamLibrary)
Gregor Mendel conducted his classic hybridization experiments on garden pea (Pisum sativum) between 1856 and 1863, establishing the fundamental laws of inheritance. He selected seven contrasting characters.
Explanation:
Trypsinogen, secreted by the pancreas, is activated to trypsin by enterokinase (intestinal enzyme). Trypsin then activates other zymogens. Pepsin is active in the stomach, rennin in infants, amylase digests starch. This cascade prevents premature protein digestion in the pancreas.
Explanation:
Biotin (vitamin B₇) is a water-soluble B vitamin that functions as a coenzyme for carboxylase enzymes, important in fatty acid synthesis and gluconeogenesis. Vitamin B₁ acts in decarboxylation, A and K are fat-soluble. Biotin is widely distributed in foods and also synthesized by gut bacteria.
Explanation:
Hybridoma technology fuses antibody-producing B cells with immortal myeloma cells to create hybridomas that produce monoclonal antibodies. Developed by Kohler and Milstein.
