Question 4

Kerala, being a coastal state in India, is highly vulnerable to the impacts of climate change. From the perspective of climate change adaptation strategies, which of the following measures would be most effective in building long-term resilience against rising sea levels and extreme weather events in the state?

Accepted Answer

B. Implementing robust early warning systems for cyclones and floods, alongside developing climate-resilient infrastructure and sustainable land-use planning. — Adaptation strategies focus on adjusting to actual or expected future climate conditions and their effects. Implementing robust early warning systems, developing climate-resilient infrastructure (e.g., seawalls, elevated buildings), and sustainable land-use planning (e.g., restricting construction in vulnerable coastal zones) are direct and effective adaptation measures for a coastal state like Kerala. Options A and C primarily relate to mitigation (reducing greenhouse gas emissions), while D is a partial measure and not comprehensive for coastal vulnerability.

Answer

A. Investing heavily in fossil fuel-based energy infrastructure to meet growing energy demands.

Answer

C. Focusing solely on reducing industrial greenhouse gas emissions from major factories within the state.

Answer

D. Promoting large-scale afforestation programs in remote, non-coastal areas only.

Question 10

Furosemide is a potent diuretic primarily used in conditions like acute pulmonary edema and severe hypertension. Its mechanism of action involves:

Accepted Answer

A. Inhibiting sodium-potassium-chloride co-transporter in the thick ascending limb of the loop of Henle — Furosemide is a loop diuretic that acts by inhibiting the Na+/K+/2Cl- co-transporter (NKCC2) in the thick ascending limb of the loop of Henle. This action prevents the reabsorption of sodium, potassium, and chloride ions, leading to a significant increase in water and electrolyte excretion. Blocking aldosterone receptors is the mechanism of potassium-sparing diuretics like spironolactone, inhibiting carbonic anhydrase is for acetazolamide, and decreasing sodium reabsorption in the distal convoluted tubule is the primary action of thiazide diuretics.

Answer

B. Blocking aldosterone receptors in the collecting duct

Answer

C. Inhibiting carbonic anhydrase in the proximal tubule

Answer

D. Decreasing sodium reabsorption in the distal convoluted tubule
