Explanation
Shifting cultivation involves clearing forest patches through slashing and burning. While sustainable at low population densities, increased pressure leads to shorter fallow periods. This prevents the soil from regenerating, causing a gradual decline in fertility and permanent deforestation. The loss of tree cover also increases vulnerability to soil erosion, negatively impacting the long-term ecological balance.I. It includes all taxes and duties collected by the Union Government.
II. Surcharges levied for purposes of the Union form a part of the divisible pool.
III. Cesses levied for specific purposes are excluded from the divisible pool.
IV. Corporation tax was included in the divisible pool following the 80th Constitutional Amendment Act.
V. The cost of collection is deducted before distributing the net proceeds.
Which of the combinations given above represents the correct statements?
Explanation
The divisible pool includes most central taxes, including corporation tax since the 80th Amendment. However, cesses and surcharges are excluded as they are reserved for the Union. To determine the actual amount shared, the cost of collection is deducted from the gross receipts. This net proceeds figure forms the basis for distribution as recommended by the commission.Explanation
An operon is a functional unit of genomic DNA found primarily in prokaryotes. It consists of a cluster of related genes under the control of a single promoter and regulatory sequences. This arrangement allows the cell to efficiently coordinate the expression of multiple proteins required for a specific metabolic pathway, ensuring they are produced simultaneously in response to environmental stimuli.| Paramara Rulers | Key Achievements/Titles |

The Constitution outlines emergency provisions in Part XVIII. Article 352 deals with National Emergency, Article 356 with State Emergency, and Article 360 with Financial Emergency.

Assertion (A): In intensive subsistence agriculture dominated by crops other than paddy, wheat and soybean are grown instead of rice.
Reason (R): Relief, climate, and soil conditions in regions like northern China and northwestern India do not support water-intensive rice cultivation. In the light of the above statements, select the correct answer from the options given below:
Explanation
In regions where rainfall is insufficient or the terrain is unsuitable for flooding fields, rice cannot be grown. Therefore, intensive subsistence farmers switch to drought-tolerant or less water-demanding crops like wheat and soybean. Northern China and parts of India illustrate this transition, where climatic constraints dictate the cultivation of alternative staple crops instead of water-intensive systems.I. Deduction of cost of collection to determine net proceeds
II. Exclusion of Cesses and Surcharges
III. Collection of gross tax revenue by the Central Board of Direct Taxes and CBIC
IV. Application of the horizontal distribution formula among States
Select the correct sequence:
Explanation
The devolution process starts with the collection of gross tax revenue by central agencies. From this, cesses and surcharges are excluded as they are not shared. Then, the costs of collection are subtracted to arrive at the net proceeds. Finally, the horizontal distribution formula is applied to determine the individual share of each state in the pool.Explanation
