Solution (By JKSSB Mock Tests)
Biodiversity hotspots are biogeographic regions with high levels of species richness and endemism that are under threat. The Western Ghats and Sri Lanka, along with the Himalayas, are recognized biodiversity hotspots in India. They harbor a vast array of flora and fauna, many of which are found nowhere else in the world, due to their unique geographical and climatic conditions.
Explanation:
Vitamin K is required for the gamma-carboxylation of prothrombin (factor II) and other clotting factors, enabling them to bind calcium and participate in coagulation. Deficiency leads to bleeding.
Explanation:
RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is the most abundant protein on Earth and the key enzyme in the Calvin cycle (C3 pathway). It catalyzes the fixation of CO2 by attaching it to Ribulose-1,5-bisphosphate (RuBP) to form a 6-carbon intermediate that immediately splits into two molecules of 3-PGA.
