Meiosis makes gametes that differ from one another, and fertilization joins a gamete from each of two parents, so every offspring gets a new mix of genes.

Work is W = F × d × cos θ, and when the angle θ between force and displacement is 90°, cos 90° = 0, so the work done is zero.

As an object comes in from far away towards C, its real, inverted image moves out from the focus towards C, and the two meet at C. For a concave mirror, an object at infinity forms its image at the focus F, and an object at the centre of curvature…

Promoting alternative development, including the growing of alternative crops in place of illicit ones, is a mandate the bureau carries under this policy, which is why the public dialogue at Malana village formed part of the operation rather than being an extra.

The Central Bureau of Narcotics is the country's apex drug law enforcement and regulatory agency and it sits under the Department of Revenue in the Ministry of Finance, a placement that surprises candidates and therefore makes a good question.

The Central Bureau of Narcotics carried out its destruction drive in Kullu district, clearing 5,165 acres, or 2,070 hectares, of illicit cannabis cultivation over one month.

The bonus was approved on the strength of the railways' performance in 2025-26, and the government cited a record freight loading of 1,670 million tonnes for that year together with a passenger count of nearly 7.41 billion.

That is the amount the Union Cabinet approved for paying a bonus of 78 days' wages to railway employees, and it is spread across 11,40,770 employees.

The Union Cabinet cleared a Productivity Linked Bonus equal to 78 days' wages for railway employees, and this is the figure every other number in the decision hangs on: the total sanctioned amount, the per-employee ceiling and the count of employees covered are all tied to the same 78 days.

The programme was launched for assistance to poor households as a way of discharging the responsibility the Central Government carries under Article 41 of the Constitution, which sits among the Directive Principles of State Policy and speaks of public assistance in old age, sickness and disablement.

The approved structure of the disability pension has two slabs by age. A beneficiary in the 0-79 years group receives Rs 375 a month, while a beneficiary who has turned 80 years or more receives Rs 625 a month, so option C matches the higher age slab asked about here.

When the Union Cabinet approved carrying the programme forward for five years, it renamed the umbrella scheme itself to Pradhan Mantri Samajik Sahayata Yojana, so option B is the one to mark.

Syngamy is the fusion of a male and a female gamete, and since each gamete is haploid, their union gives a diploid zygote.

Humans have a single functional insulin gene, INS, on the short arm of chromosome 11, and both chains of insulin come from it.

One nanometre is 10⁻⁹ metre, and since one metre is 100 (10²) centimetres, it equals 10⁻⁷ centimetre. The prefix nano means one billionth.

Saturated open-chain hydrocarbons are the alkanes, and every alkane fits the formula CₙH₂ₙ₊₂. In a saturated hydrocarbon every carbon atom is joined to others only by single bonds, so each carbon holds the largest possible number of hydrogen atoms.

Elephantiasis, or lymphatic filariasis, is an endemic disease: it stays steadily present in certain regions and develops slowly over years, rather than breaking out suddenly in a large number of people.

The spring constant is force divided by extension, so its SI unit is newton per metre. Hooke's law says that, within the elastic limit, the restoring force of a spring is proportional to how far it is stretched or compressed: F = −kx.

Mission Indradhanush was launched in December 2014 to bring every child under two years and every pregnant woman under full immunisation against vaccine-preventable diseases.

The wave travels at 1,200 m/s, so 2,400 m takes 2 seconds. The speed of any wave is the product of its frequency and wavelength: v = fλ.
