The intestinal enzyme that converts trypsinogen to trypsin is: MCQ with Answer and Explanation

Explanation:
The vascular cambium is a thin layer of meristematic cells located between the primary xylem and primary phloem in the vascular bundles of dicot stems and roots, and in the secondary vascular tissue. It is a lateral meristem that divides periclinally (parallel to the surface). It produces secondary xylem (wood) cells towards the inside (center) of the stem or root, and secondary phloem (inner bark) cells towards the outside (periphery). Since it produces xylem much faster than phloem, the secondary xylem accumulates and forms the bulk of the wood.

Explanation:
Angiogenesis is the growth of new blood vessels from pre-existing ones, important in development, wound healing, and tumor growth. Vasodilation is widening, vasoconstriction narrowing of vessels. Hematopoiesis is blood cell formation. Inhibiting angiogenesis is a cancer therapy strategy.

Explanation:
Metabolism, comprising anabolism and catabolism, is a universal feature of all living cells. Non-living objects may possess mass, crystallize, or conduct electricity, but they lack metabolic processes. Metabolism involves enzyme-catalyzed biochemical reactions that sustain life. Thus, metabolic activity is a definitive characteristic of life.
