Question 1 of 5
1. Question
2 points1. Consider the following statements regarding Pyrolysis:
1. It is a process of chemically decomposing materials at high temperatures.
2. In this process, the oxygen is used to attain high temperatures.
Which of the above- given statements is/are correct?Correct
Answer: A
Explanation:
Statement 1 is correct: The process typically occurs at temperatures above 430 °C (800 °F) and under pressure. It simultaneously involves the change of physical phase and chemical composition of organic material. Pyrolysis is an irreversible process. Pyrolysis is used to convert biomass into Synthesis Gas or Syngas and biochar.
Statement 2 is incorrect: Pyrolysis is a process of chemically decomposing organic materials at elevated temperatures in the absence of oxygen.Incorrect

2. Question
2 points2. What is “Winchcombe”?
Correct
Answer: D
Explanation:
Option D is correct: Winchcombe is a meteorite. A piece of the Winchcombe meteorite had touched down in the town of Winchcombe in Gloucestershire in the UK in February 2021.
⮚ The difference between a meteor, meteorite and meteoroid is nothing but where the object is:
● Meteoroids are objects in space that range in size from dust grains to small asteroids.
● But when meteoroids enter the Earth’s atmosphere, they are called meteors.
● But if a meteoroid enters the Earth’s atmosphere and hits the ground, it is called a meteorite.Incorrect

Question 3 of 5
3. Question
2 points3. With reference to Monoclonal antibodies, consider the following statements:
1. They are laboratory-made proteins that mimic the immune system’s ability to fight off harmful pathogens such as viruses.
2. It is not possible to produce monoclonal antibodies that specifically bind to virtually any suitable substance.
Which of the statements given above is/are correct?Correct
Answer: A
Explanation:
Statement 1 is correct: Monoclonal antibodies are laboratory-made proteins that mimic the immune system’s ability to fight off harmful pathogens such as viruses. They are artificially created antibodies that aim to aid the body’s natural immune system. They target a specific antigen — a protein from the pathogen that induces an immune response.
Statement 2 is incorrect: Monoclonal antibodies can be created in the lab by exposing white blood cells to a particular antigen. To increase the number of antibodies produced, a single white blood cell is cloned, which in turn is used to create identical copies of the antibodies. In the case of Covid-19, scientists usually work with the spike protein of the SARS-CoV-2 virus, which facilitates the entry of the virus into the host cell. It is possible to produce monoclonal antibodies that specifically bind to virtually any suitable substance; they can then serve to detect or purify it. This capability has become an important tool in biochemistry, molecular biology, and medicine.Incorrect

4. Question
2 points4. Which of the following statements correctly describes Kabasura Kudineer?
Correct
Answer: A
Explanation:
Statement A is correct:Kabasura Kudineer is a traditional formulation used by Siddha practitioners for managing common respiratory health. It is an herbal mixture of various ingredients or elements. It comprises dry ingredients of ginger, pippali, clove, kadukkai, ajwain and many other herbs. Kabasura Kudineer has been found to be useful in the treatment of asymptomatic, mild, and moderate COVID-19 infection cases. The AYUSH Ministry launched a massive nationwide campaign to distribute Kabasura Kudineer.Incorrect

Question 5 of 5
5. Question
2 points5. The correct description of Protein–Antibody Conjugates (PAC) is:
Correct
Answer: D
Explanation:
Option D is correct: This is a new concept of combining two different approaches to drug delivery. Biological drugs and Antibody-Drug Conjugates (ADC). Both these methods combined to produce Protein–Antibody Conjugate or PACs. This PAC can be used for targeted drug delivery. Protein‐antibody conjugates (PACs) are used for antibody‐directed delivery of protein to specific cells. This method ensures the precise and effective delivery of drugs to specific cells. Hence, this method could have an impact on treating diseases like pancreatic cancer.Incorrect
