The Doctrine of Lapse was a policy that allowed the British to annex any princely state if the ruler died without a male heir, which contributed to the discontent leading to the Rebellion of 1857.

The Integrated Rural Development Programme was launched in the 1970s to provide employment and promote self-reliance among the rural poor.

Lead is a heavy metal that can be toxic to humans and the environment.

Volatile Organic Compounds (VOCs) are major contributors to smog formation, especially in urban areas.

Ozone at ground level is a major component of smog, formed by the reaction of sunlight with pollutants.

Nitrogen Dioxide is a major contributor to the formation of smog, particularly in urban areas.

Nitrogen Dioxide (NO2) is associated with respiratory problems and is a significant air pollutant.

Sulfur oxides (SOx) and nitrogen oxides (NOx) are the main pollutants that contribute to the formation of acid rain.

Nitrogen dioxide is a key contributor to the formation of smog, especially in urban areas.

A concave hexagon has at least one interior angle greater than 180 degrees, which makes it a non-convex polygon.

A star-shaped polygon has at least one interior angle greater than 180 degrees, making it concave.

Nylon is known for its high tensile strength and is commonly used in textiles and ropes.

Nylon-6,6 is produced by condensation polymerization, involving the reaction of diamines and dicarboxylic acids.

Polyisoprene is a key polymer used in the production of synthetic rubber.

The polynomial x^2 + 4x + 4 can be factored as (x + 2)^2, making it a perfect square.

A quadratic polynomial is defined as a polynomial of degree 2, which is 2x^2 + 3x - 5.

Sustainable tourism can help conserve biodiversity by promoting responsible travel that does not harm ecosystems.

Sustainable agriculture practices help in conserving biodiversity by maintaining healthy ecosystems.

Rainwater harvesting is a practice that helps conserve water and can support ecosystems by maintaining water levels.

Crop rotation helps maintain soil health and reduces soil erosion by preventing nutrient depletion.

Speciation can occur through various processes, including geographic, behavioral, and temporal isolation, leading to the formation of new species.

Dissolving salt in water is a spontaneous process at standard conditions, resulting in a negative ΔG.

Photosynthesis is an endothermic process that requires energy, resulting in a positive ΔG.

The melting of ice increases the entropy of the system as it transitions from a solid to a liquid state, which has more disorder.

Condensation is the process where gas changes to liquid.

In an adiabatic process, the system does not exchange heat with its surroundings, leading to a change in temperature.
