The stomach secretes the enzyme pepsin to aid digestion. Pepsin mainly acts on which nutrient?

  1. AOption (a)

    Proteins

  2. BOption (b)

    Carbohydrates

  3. COption (c)

    Fats

  4. DOption (d)

    Vitamins

View answer & explanation

Correct answer

Answer: (a)A.

Proteins

Why this answer is correct

The correct answer is Proteins.

Key Points

  • Pepsin is a powerful enzyme found in Gastric Juice that initiates the digestion of proteins by breaking them down into smaller units called Peptones and Proteoses.
  • It is secreted by the Chief Cells (peptic cells) of the stomach lining in an inactive proenzyme form known as Pepsinogen.
  • The activation of Pepsinogen into Pepsin requires an acidic medium, which is provided by Hydrochloric Acid (HCl) secreted by the Oxyntic Cells (parietal cells).
  • The stomach maintains a highly acidic pH level (approximately 1.8), which is the optimum environment for Pepsin to function efficiently as an Endopeptidase.
  • By hydrolyzing internal peptide bonds, Pepsin transforms long-chain complex Proteins into shorter polypeptide chains, facilitating further digestion in the Small Intestine.

 Additional Information

  • Carbohydrates:
  • Digestion begins in the Buccal Cavity through the action of Salivary Amylase (Ptyalin).
  • Final breakdown into simple sugars like Glucose occurs in the small intestine via Pancreatic Amylase and Disaccharidases.
  • Fats:
  • Requires Emulsification by Bile Salts produced in the Liver and stored in the Gallbladder.
  • The enzyme Lipase, primarily from the Pancreas, breaks down fats into Fatty Acids and Glycerol.
  • Vitamins:
  • These are Micronutrients essential for metabolic functions but do not require enzymatic breakdown for energy.
  • They are absorbed directly in the Small Intestine, specifically in the Ileum for Vitamin B12.

Frequencies higher than the human audible limit of 20,000 Hz are classified as _____.

  1. AOption (a)

    Infrasound

  2. BOption (b)

    Supersonic

  3. COption (c)

    Tones

  4. DOption (d)

    Ultrasound

View answer & explanation

Correct answer

Answer: (d)D.

Ultrasound

Why this answer is correct

The correct answer is Ultrasound.

Key Points

  • The human auditory system is sensitive to a specific range of vibrations known as the audible range, which typically spans from 20 Hz to 20,000 Hz.
  • Sound waves with frequencies that surpass the upper limit of 20,000 Hz (or 20 kHz) are scientifically classified as ultrasound or ultrasonic waves.
  • While these waves are physically identical to audible sound in terms of propagation, they are inaudible to the human ear because the tympanic membrane cannot vibrate at such high speeds.
  • Many animals, including bats, dolphins, and porpoises, have the biological capability to produce and hear ultrasound, utilizing it for echolocation to hunt and navigate.
  • The Hertz (Hz) is the standard SI unit of frequency, representing the number of cycles per second; thus, ultrasound involves over 20,000 vibrations every second.

 Additional Information

  • Infrasound:
  • Refers to sound waves with a frequency below 20 Hz, which is the lower limit of human hearing.
  • Sources include seismic waves from earthquakes, volcanic eruptions, and ocean tides.
  • Large mammals like elephants and rhinoceroses communicate using infrasonic signals over vast distances.
  • Supersonic:
  • This term describes the velocity of an object rather than its frequency. An object is supersonic if it travels faster than the speed of sound (approximately 343 m/s in air).
  • When an aircraft reaches supersonic speeds, it produces a sonic boom due to the accumulation of shock waves.
  • Tones:
  • A tone is a sound that consists of a single, pure frequency. Most musical sounds are actually "notes," which combine a fundamental frequency with several harmonics.
  • Practical Applications of Ultrasound:
  • Medical Imaging: Utilized in sonography to visualize fetuses and internal organs without ionizing radiation.
  • SONAR: Used by submarines and ships to detect underwater obstacles and measure the depth of the sea.
  • Industrial Cleaning: High-frequency vibrations are used to remove contaminants from delicate electronic components and surgical instruments.

    Ozone

  3. COption (c)

    Ammonia

  4. DOption (d)

    Sulphur dioxide

View answer & explanation

Correct answer

Answer: (d)D.

Sulphur dioxide

Why this answer is correct

The correct answer is Sulphur dioxide.

Key Points

  • Acid rain refers to any form of precipitation, including rain, snow, or fog, that contains elevated levels of nitric and sulphuric acids.
  • The primary chemical responsible for this phenomenon is Sulphur dioxide (SO2), which is released into the atmosphere through the combustion of fossil fuels (like coal and oil) in power plants and industrial boilers.
  • Once in the atmosphere, SO2 reacts with water vapor, oxygen, and other chemicals to form Sulphuric acid (H2SO4), which eventually falls to the ground as acid rain.
  • While normal rainwater is slightly acidic with a pH value of about 5.6 (due to dissolved Carbon dioxide), acid rain typically has a pH value between 4.2 and 4.4.
  • The environmental impact of acid rain includes the acidification of aquatic environments, damage to forest vegetation, and the chemical weathering of stone buildings and cultural monuments like the Taj Mahal.

 Additional Information

  • Carbon monoxide (CO):
  • A colorless, odorless, and highly toxic gas produced by the incomplete combustion of carbon-based fuels.
  • It does not directly contribute to acid rain but poses significant health risks by reducing the oxygen-carrying capacity of blood.
  • Ozone (O3):
  • Found in the troposphere, it acts as a secondary pollutant and a major component of photochemical smog.
  • While it helps catalyze some atmospheric oxidation processes, it is not a direct precursor to acid rain formation.
  • Ammonia (NH3):
  • An alkaline gas primarily emitted from agricultural activities, livestock management, and fertilizer use.
  • In the atmosphere, it can act as a buffering agent to neutralize acidic compounds, though its deposition can still lead to soil and water issues.

Key Points

  • An ecosystem is considered the structural and functional unit of nature because it encompasses the complex interactions between living organisms and their physical environment.
  • The term was coined by A.G. Tansley in 1935 to describe a self-regulating and self-sustaining system.
  • The structural features of an ecosystem consist of biotic components (producers, consumers, and decomposers) and abiotic components (temperature, light, water, and soil).
  • The functional aspects of an ecosystem include energy flow, nutrient cycling, productivity, and decomposition, which ensure the continuity of life within a specific geographical area.
  • Ecosystems can vary significantly in scale, ranging from a small pond or a single tree to vast biomes like tropical rainforests or the entire biosphere.

 Additional Information

  • Environment:
  • It refers to the sum total of all external conditions (physical, chemical, and biological) that surround and influence an organism.
  • While it provides the setting for life, it lacks the specific internal functional cycles that define an ecosystem.
  • Cell:
  • The cell is the fundamental structural and functional unit of life or living organisms, not of nature as a whole.
  • All living things are composed of cells, and the study of these units is known as Cytology.
  • Ecology:
  • Ecology is the scientific study of the relationships and interactions between organisms and their environment.
  • The concept was popularized by Ernst Haeckel in 1866, who defined it as the study of the economy of nature.

  • The defining soil characteristic of this region is permafrost, which refers to ground, including rock or soil, that remains at or below 0°C for at least two consecutive years.
  • Due to the presence of permafrost and a very short growing season, deep-rooted trees cannot survive; instead, the landscape is dominated by low-lying vegetation such as mosses, lichens, and small sedges.
  • In the Koppen climate classification, the ET designation is primarily found in the high latitudes of the Northern Hemisphere, covering the Arctic coastal fringes of North America, Eurasia, and the Antarctic Peninsula.
  • The moisture levels in these regions are low, making it a polar desert, but the low evaporation rates allow the soil to remain moist or waterlogged during the brief summer thaw.

 Additional Information

  • Cfb - Marine West Coast Climate:
  • Characterized by mild winters and cool summers with high humidity and year-round precipitation.
  • Supports dense temperate forests, including both deciduous and coniferous trees, primarily in Western Europe and the Pacific Northwest.
  • Aw - Tropical Wet and Dry Climate:
  • Also known as the Savanna climate, it features a distinct dry season during the winter months.
  • The vegetation consists of tall grasses and scattered, drought-resistant trees like the Acacia or Baobab.
  • BSh - Subtropical Steppe Climate:
  • A semi-arid climate that serves as a transition zone between desert (BW) and more humid climates.
  • It experiences high temperatures and erratic rainfall, supporting short-grass prairies and xerophytic shrubs.

BIRSA 101

Why this answer is correct

The correct answer is BIRSA 101.

Key Points

  • BIRSA 101 is India’s first indigenous CRISPR-Cas9 based gene therapy specifically designed to provide a curative treatment for Sickle Cell Disease (SCD).
  • Launched in November 2025, the therapy represents a major breakthrough in India’s Atmanirbhar Bharat initiative in the field of advanced biotechnology and genomic medicine.
  • The therapy was developed through a collaborative research effort led by the Council of Scientific and Industrial Research (CSIR) and the Institute of Genomics and Integrative Biology (IGIB), aimed at making expensive gene treatments affordable for the Indian population.
  • The treatment mechanism involves harvesting the patient’s own hematopoietic stem cells, using CRISPR technology to edit the HBB gene or induce fetal hemoglobin (HbF), and then re-infusing them to produce healthy red blood cells.
  • The naming of BIRSA 101 pays tribute to the tribal leader Birsa Munda, reflecting the therapy's primary target demographic, as Sickle Cell Disease disproportionately affects Scheduled Tribes across the tribal belt of India.

 Additional Information

  • Sickle Cell Disease (SCD):
  • It is an inherited genetic blood disorder where red blood cells become rigid and sickle-shaped, leading to anemia, organ damage, and vaso-occlusive crises.
  • India has the second-highest global burden of SCD, with a high prevalence in states like Madhya Pradesh, Gujarat, and Chhattisgarh.
  • CRISPR Technology:
  • Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) serves as a molecular scissor to edit DNA with high precision.
  • It utilizes a guide RNA to identify the target genetic sequence and the Cas9 enzyme to execute the cut, allowing for the correction of genetic mutations.
  • National Sickle Cell Anaemia Elimination Mission:
  • Announced in the Union Budget 2023-24 and launched in July 2023, the mission aims to eliminate the disease as a public health threat by 2047.

  4. DOption (d)

    Through opinion polls and industrial development trends

View answer & explanation

Correct answer

Answer: (b)B.

Combining emissions, energy use and expert-reviewed climate policy data

Why this answer is correct

The correct answer is Combining emissions, energy use and expert-reviewed climate policy data.

Key Points

  • The Climate Change Performance Index (CCPI) 2025 is an independent monitoring tool that evaluates the climate protection performance of 63 countries and the European Union, which together account for more than 90% of global greenhouse gas emissions.
  • The assessment framework is divided into four distinct categories with specific weightings: Greenhouse Gas (GHG) Emissions (40%), Renewable Energy (20%), Energy Use (20%), and Climate Policy (20%).
  • The GHG Emissions indicator tracks current emission levels, recent trends, and the alignment of national 2030 targets with the Paris Agreement goal of limiting global warming to 1.5 degrees Celsius.
  • The Climate Policy component is unique because it incorporates qualitative data through expert-reviewed assessments provided by approximately 450 climate and energy experts from non-governmental organizations and think tanks.
  • The index uses a standardized methodology to provide a comparable score for each country, determining whether their progress is Very High, High, Medium, Low, or Very Low.

 Additional Information

  • Publication and Authorship:
  • The index is published annually by Germanwatch, the NewClimate Institute, and the Climate Action Network (CAN) International.
  • The CCPI 2025 report was officially released during the COP29 summit held in Baku, Azerbaijan.
  • Methodological Limitations of Other Approaches:
  • Renewable Energy statistics only: This metric alone is insufficient as it does not account for the total carbon footprint or energy efficiency.
  • Forest Cover and National Targets: While important for carbon sequestration, forest data is not a primary pillar of the CCPI, which prioritizes energy-related emissions and systemic decarbonization.
  • Opinion Polls: Public sentiment is not a factor in the CCPI; it relies strictly on hard data from the International Energy Agency (IEA) and professional policy critiques.
