JKPSC General Studies MCQs

Explanation

Statement I is Correct: DNA (Deoxyribonucleic acid) is the primary molecule that stores and transmits genetic information in almost all living organisms.

Statement II is Incorrect: While some specific viruses have double-stranded RNA, RNA is typically a single-stranded molecule in most biological roles (like mRNA, tRNA, and rRNA).

Statement III is Correct: Mitosis is a type of cell division that results in two identical daughter cells. This process is essential for the growth of multicellular organisms and the repair of tissues

Explanation

1. Amylase — carbohydrates (Correct): Amylase is produced in the salivary glands and the pancreas. Its primary role is to break down complex carbohydrates (starches) into simpler sugars like maltose.

2. Lipase — proteins (Incorrect): Lipase is the enzyme responsible for breaking down fats (lipids) into fatty acids and glycerol.

3. Pepsin — fats (Incorrect): Pepsin is an enzyme found in the stomach that breaks down proteins into smaller peptides.

Explanation

A) Incorrect: Viruses are obligate intracellular parasites. They lack the cellular machinery (like ribosomes) to produce energy or proteins and therefore cannot reproduce independently outside a living host cell.

B) Correct: Bacteria are single-celled organisms that have all the necessary genetic material and metabolic pathways to live independently. They primarily reproduce asexually through a process called binary fission, where one parent cell divides into two identical daughter cells.

C) Incorrect: Bacteria are unicellular (single-celled). Viruses are acellular (not composed of cells at all) and are often described as genetic material wrapped in a protein coat.

D) Incorrect: While bacteria are visible under a standard light microscope, most viruses are far too small (typically 20–300 nm) to be seen with one. They generally require an electron microscope for visualization.

Explanation

• I. Reflection and refraction are optical phenomena. (Correct)

• II. Both reflection and refraction involve a change in the speed of light. (Incorrect: Reflection happens in the same medium, so speed doesn't change; only refraction involves a speed change between media).

• III. Refraction bends the path of light. (Correct)

• Correct Option: C) Only I and III are correct.

Explanation

IMPORTANT! This question has been marked as deleted in final answer key.

This may be because "Reason (R): Acceleration due to gravity is independent of the mass of the object" does not clarify which object we are talking about. It is independent of mass of falling object but depends upon mass of pulling object as g= GM/r^2

Explanation

• Statement I is correct: The HPI-1 was indeed designed to measure human poverty in developing countries, focusing on deprivation in three essential dimensions: longevity (vulnerability to death at an early age), knowledge (exclusion from the world of reading and communication), and standard of living (lack of access to basic necessities).

• Statement II is correct: The HPI-2 was used for selected industrialized countries and included an additional, fourth dimension of social exclusion, in addition to the three HPI-1 dimensions.

• Statement III is correct: The Human Poverty Index (HPI) was replaced by the Multidimensional Poverty Index (MPI) in the 2010 Human Development Report, which provides a more comprehensive measure of poverty.

Explanation

The longitudinal extent of India spans from the westernmost point in Gujarat to the easternmost point in Arunachal Pradesh. This range is approximately \(29^{\circ }\) and is specifically defined as \(68^{\circ }7^{\prime }\) E to \(97^{\circ }25^{\prime }\) E. This wide longitudinal gap causes a time difference of about two hours between the extreme eastern and western parts of the country.

Explanation

Statement-1 is correct; the Surinsar-Mansar lake was designated as a Ramsar site in 2005.

Statement-2 is incorrect; the site is known to host migratory birds, including 15 species of migratory waterfowl.

Statement-3 is correct; the lake has a rich diversity of aquatic fauna, including various fish species, and is an important wetland ecosystem.
