Equalization grants ensure minimum service standards everywhere. The divisible pool consists of central taxes shared with states. Together, these tools form the basis for equitable financial distribution and sustainable national growth.Explanation
In the standard B-DNA double helix model, the vertical distance between two adjacent nitrogenous base pairs is approximately 0.34 nanometers. This precise spacing contributes to the overall stability of the helix through base-stacking interactions. Given that one full helical turn covers 3.4 nanometers and contains ten base pairs, the calculated distance between individual steps remains remarkably consistent.I. He defeated the Malwa Sultan Mahmud Khalji II in the Battle of Gagron.
II. He defeated Ibrahim Lodi in the Battle of Khatoli.

Kautilya emphasized an extensive espionage network as crucial for the survival and stability of the Mauryan state. Spies were strategically deployed to gather intelligence on foreign powers, monitor the loyalty of high officials, and identify potential domestic unrest. This centralized intelligence system allowed the monarch to take preemptive actions against internal conspiracies and external threats, ensuring the overall security of the administration.Explanation
The value of an MLA’s vote in the Presidential election is calculated based on the state’s population and the number of elected assembly members. For Rajasthan, this value is fixed at 129. These values were determined using 1971 census data and will remain unchanged until the first census taken after 2026, ensuring uniformity and parity across different states.I. Dry land farming is practiced in regions receiving less than 75 cm of annual rainfall.
II. Drought-resistant crops like millets and gram are typical of dry land farming.
III. Irrigated farming often faces the ecological problem of soil salinization.
IV. Irrigated farming is completely independent of the nature of the soil.
Which of the above statement(s) is/are correct?
Explanation
Dry land farming occurs in low-rainfall areas, focusing on moisture conservation and drought-resistant crops like millets. Irrigated farming provides reliable water but can lead to soil salinization through poor drainage and evaporation. While irrigation reduces weather dependency, soil characteristics still significantly influence crop selection and drainage requirements, making soil type a critical factor.Explanation
