ANSWERS TO MCQS
1 C)
FOR YOUR INFORMATION:
— Our physique produces antibodies, that are proteins, to combat a viral an infection.
— Monoclonal antibodies are synthetic antibodies that mimic the exercise of our immune system. Subsequently, assertion 1 is right.
— They’re produced by a course of that entails extracting particular antibodies from human blood after which cloning them.
— These monoclonal antibodies are designed to particularly goal a virus or a selected a part of it. For instance, the Spike protein of SARS-CoV-2 is the goal of the cocktail of two monoclonal antibodies referred to as REGEN-COV2. Assertion 2 is due to this fact right.
— Monoclonal antibodies bind to particular components of the Spike protein, blocking its capability to contaminate wholesome cells. Assertion 4 is due to this fact right.
— Along with Covid-19, monoclonal antibodies have been used within the remedy of cancers in addition to Ebola and HIV. Subsequently, assertion 3 just isn’t right.
Subsequently, choice (c) is the right reply.
2.(a)
FOR YOUR INFORMATION:
— Bennu and different near-Earth asteroids may very well be harmful to Earth, so precisely predicting their orbits is important.
— Yarkovsky impact is a phenomenon that adjustments the trajectory of a celestial object attributable to uneven radiation of thermal power.
— The day aspect of a rotating asteroid heats up when daylight hits it; Because the asteroid rotates, the evening aspect cools and releases warmth, making a small thrust that, over time, can change the path of the asteroid.
— Traits reminiscent of the form, brightness and floor traits of an asteroid affect the Yarkovsky impact, and understanding how will enable scientists to raised predict the orbit of Bennu and different near-Earth asteroids.
Subsequently, choice (a) is the right reply.

3.(a)
FOR YOUR INFORMATION:
— Hydrogen, the commonest aspect in nature, exists solely together with different components and should be extracted from pure compounds like water (which is a mix of two hydrogen atoms and of an oxygen atom).
— Hydrogen produced from fossil fuels is known as grey hydrogenwhich constitutes many of the hydrogen produced right now. Subsequently, assertion 1 just isn’t right.
— Hydrogen produced from fossil fuels with carbon seize and storage choices is known as blue hydrogen.
— Inexperienced hydrogen is hydrogen fuel produced by water electrolysis – an energy-intensive course of for splitting water into hydrogen and oxygen – utilizing renewable power to do it.
— India has an bold venture Inexperienced Hydrogen Mission which goals to supply 5 million tonnes of gas per yr from 2030. Assertion 2 is due to this fact not right.
— Inexperienced hydrogen has explicit benefits:
(i) It’s a clean-burning molecule that can be utilized to decarbonize numerous industries, reminiscent of transportation, chemical substances, iron and metal. Subsequently, assertion 3 is right.
(ii) Hydrogen may be produced by channeling renewable power that the grid is unable to retailer or use.
Subsequently, choice (a) is the right reply.
4.(b)
FOR YOUR INFORMATION:
– THE CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite tv for pc Commentary) has recorded greater than 10 billion LIDAR measurements and contributed to the creation of 1000’s of scientific stories throughout its 17 years of operation.
— It was collectively launched by NASA and CNES (Nationwide Middle for Area Research) in addition to the cloud profiling radar system on the CloudSat satellite tv for pc. Subsequently, assertion 1 just isn’t right.
— The satellite tv for pc’s Lidar and radar devices direct power beams towards Earth and observe their reflection off clouds and atmospheric aerosols. Assertion 2 is due to this fact right.
— The 2 satellites had been launched on April 28, 2003 and circled the planet in a sun-synchronous orbit from the North Pole to the South Pole. Subsequently, assertion 3 is right.
— They measured the altitude of clouds and layers of airborne particles like mud, sea salt, ash and soot whereas probing the “vertical construction” of the environment.
— Scientists had been capable of develop more and more advanced fashions to grasp advanced atmospheric processes reminiscent of particle transport, precipitation, cloud formation and atmospheric convection because of observations from the 2 satellites.
