1 is incorrect. Simlipal Biosphere reserve is situated in the northern part of Odisha’s Mayurbhanj district. Reserve lies in the eastern end of the eastern ghat.

Statement 2 is correct. Summer season coincides with the shedding of deciduous forests in the forest areas. The fallen leaves are more vulnerable to catching fire and facilitate the spreading of these forest fires quickly over the entire forest area.

Option 1 is correct. poachers set a small patch of forest on fire to divert the wild animals can lead to such fires. They do not douse the fire after hunting leading to forest fires.

Option 2 is correct. The fallen leaves are more vulnerable to catching fire and facilitate the spreading of these forest fires quickly over the entire forest area.

Option 3 is incorrect. Dry leaves and high temperature are requirements for forest fire. In Winters high temperature and dry leaves on the forest floor are not available.

INSTC is a 7,200-km-long multi-modal connectivity project to establish transport networks (ship, rail, and road route). It will be used for moving freight between India, Russia, Iran, Europe, and Central Asia. It will cut costs and time in moving cargo.

It includes 13 countries namely India, Iran, Russia, Turkey, Armenia, Azerbaijan, Belarus, Kazakhstan, the Kyrgyz Republic, Tajikistan, Oman, Syria, and Ukraine.

Statement 1 is correct. Black Browed Babbler is a songbird species in the family of Pellorneidae.

Statement 2 is correct. The single specimen of the bird was first found between 1843 through 1848 during an expedition. However, after that, the species was never seen in the wild again. Significance: The bird is known for the longest known missing period (170 years) for any Asian species. It is also often called ‘the biggest enigma in Indonesian ornithology’.

Statement 3 is incorrect. It is Classified as Data Deficient in the IUCN Red List (BirdLife International 2020).

Statement 1 is correct. Spectrograph is an instrument that obtains and records an astronomical spectrum. It separates incoming light by its wavelength or frequency. It records the resulting spectrum in multichannel detectors like a photographic plate for analysis.

Statement 2 is incorrect. Indian scientists indigenously designed and developed a low-cost optical spectrograph named “Aries-Devasthal Faint Object Spectrograph & Camera (ADFOSC)”.

Statement 3 is incorrect. The spectrograph can locate sources of faint light from:

Distant galaxies in a very young universe

Regions around supermassive black-holes around the galaxies

Cosmic explosions like supernovae, young and massive stars and faint dwarf galaxies.

Exercise Desert Flag is an annual multinational large force employment warfare exercise. United Arab Emirates Air Force hosts this exercise.

Participating Countries: Ten countries including India, the United Arab Emirates, the USA, France, Saudi Arabia, South Korea, and Bahrain are participating in the exercise.

This is the first time India will participate in Exercise Desert Flag. Further, It is also the first time India is taking part in a multinational air combat exercise in the strategically located Persian Gulf region.

Statement 1 is correct. CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology is a tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function.

CRISPRs are specialized stretches of DNA. The protein Cas9 (CRISPR-associated-9) is an enzyme that acts like a pair of molecular scissors, capable of cutting strands of DNA.

Its many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops.

Statement 2 is correct. The Tata CRISPR test, powered by CSIR-IGIB (Institute of Genomics and Integrative Biology) FELUDA, received regulatory approvals recently from the Drug Controller General of India (DCGI) for commercial launch.

The Tata CRISPR test is the world’s first diagnostic test to deploy a specially adapted Cas9 protein to successfully detect the virus causing Covid-19.

The Tata CRISPR test achieves accuracy levels of traditional RT-PCR tests, with quicker turnaround time, less expensive equipment, and better ease of use.

# CRISPR technology was adapted from the natural defense mechanisms of bacteria and archaea (the domain of single-celled microorganisms). These organisms use CRISPR-derived RNA and various Cas proteins, including Cas9, to foil attacks by viruses and other foreign bodies. They do so primarily by chopping up and destroying the DNA of a foreign invader. When these components are transferred into other, more complex, organisms, it allows for the manipulation of genes, or “editi

Option 1 is incorrectly matched. Kibithu or Kibithoo is a town in Arunachal Pradesh in Anjaw district. It is one of the easternmost permanently populated towns of India.

Option 2 is incorrectly matched. Sumdorong Chu is a tributary of the Nyamjang Chu River that flows along the India-China border between the Tibet and the Tawang district of Arunachal Pradesh.

Option 3 is correctly matched. Pasighat is in the East Siang district in the Indian state of Arunachal Pradesh.

Statement 1 is correct. The immune system develops a defense against antigens, which are substances that can stimulate the immune system. This defense is known as the immune response and usually involves the production of:

–Protein molecules (immunoglobulins or antibodies, the major component of humoral immunity) by B-lymphocytes (B-cells)

-Specific cells, including T-lymphocytes (also known as cell-mediated immunity).

Statement 2 is correct. There are five immunoglobulin classes (isotypes) of antibody molecules: IgG, IgM, IgA, IgE, and IgD.

–Immunoglobulin A (IgA), which is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract, as well as in saliva and tears.

–Immunoglobulin G (IgG), the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections.

–Immunoglobulin M (IgM), which is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection.

–Immunoglobulin E (IgE), which is associated mainly with allergic reactions. It is found in the lungs, skin, and mucous membranes.

–Immunoglobulin D (IgD) exists in small amounts in the blood.
