———- uses a person’s own stem cells for treatment, while in the allogeneic procedure, a donor donates stem cells
An autologous transplant
Recently, ISRO has started the development of ——- for power generation and thermal management of ISRO’s deep space missions. In this context, consider the following statements:
- It is a type of Nuclear-based power system that converts thermal energy to electrical energy through thermocouples.
- Plutonium-238 is used as fuel.
- It is used for deep space missions.
a Radioisotope Thermoelectric Generator (RTG).

SWADESH
Blue Hydrogen is derived from natural gas through the process of
steam methane reforming(SMR).
The 2021 Nobel Prize in Physiology or Medicine was awarded jointly to David Julius and Ardem Patapoutian for their discoveries of
receptors for temperature and touch. TRPV1 and TRPM8
Viral vector vaccines are relatively complex to manufacture and previous exposure to the vector could….. the effectiveness of the vaccine

Prokaryotic cells
The Nobel Prize in Chemistry 2021 was awarded to Benjamin List and David MacMillan for the development of a precise new tool for molecular construction:
organocatalysis.
…..is the synthesis of RNA from DNA.
Transcription
The hotter air is lighter (less dense) than the cooler air above it and has a refractive index slightly… than that of the cooler air.

Referred to as NASA’s new eye in the sky, This Earth-observing satellite is a joint mission of NASA and the United States Geological Survey. The mission aims to study climate change and is a continuation of a series of Earth-observing spacecraft stretching back almost 50 years.
Identify the satellite system from the passage given above.
(a) Landsat-9
…..is the reciprocal of electrical conductivity. It is the measure of the ability of a material to oppose the flow of current.
Electrical resistivity
In the context of astronomy, with reference to earth, a Quasi Satellite is an
(a) object that orbits the Sun with orbital period similar to that of the Earth.
When light traveling through the air enters a different medium, such as glass or water, the speed and wavelength of light are….., although the frequency remains unaltered
reduced
Nobel prize in physics
1) for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales
2) for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”

Recently launched by SpaceX’s Dragon spacecraft, the mission is the first all civilian, non government space expedition. It orbited around the Earth higher than the Hubble Telescope for 3 days. The mission is a part of an effort to raise funds for pediatric treatment and research facility that focuses on children’s catastrophic diseases, particularly leukemia and other cancers.
Identify the space mission from the passage given above.
(c) Inspiration4
Every object in the universe attracts every other object with a force that is proportional to the product of their masses and inversely proportional to
the square of the distance between them.
R.H. will be…. when the dew point and the ambient temperature are the same.
100%
At dew point air will be at its maximum capacity to hold moisture and hence Relative Humidity will be 100%
Being India’s first privately developed cryogenic rocket engine. It is completely 3D printed. The engine developed by a Hyderabad-based start-up Skyroot Aerospace uses Liquid Natural gas (LNG) and Liquid Oxygen (LoX) as propellants.
Identify the system from the passage given above.
