23. Which of the following statements is/are correct about vaccination that provides protection against an infectious disease?

1. It blocks the entry of the infectious agent into body.
2. It produces antibodies against infection.
3. It kills the infectious agent when it enters in the body.

Select the correct answer using the codes given below.

Correct Answer: (b) Only 2
Solution:Only Statement 2 is correct. It produces antibodies against infection. Vaccination stimulates the production of antibodies specific to the pathogen.

Antibodies are proteins that bind to the infectious agent, neutralizing it and preventing it from causing harm. These antibodies remain in your system, ready to respond if you encounter the pathogen again.

Statements 1 and 3 are incorrect and can be corrected as Vaccination does not directly block the entry of infectious agents into the body. Instead, it prepares the immune system to recognise and respond effectively when the infectious agent (such as a virus or bacteria) enters. Vaccination itself does not directly kill the infectious agent. Instead, it primes your immune system to recognise and fight the pathogen effectively.

24. Which cells in human body have no nucleus?

Correct Answer: (c) Red blood cells
Solution:Red blood cells in human body do not have nucleus.

Red blood cells are produced in the bone marrow and they have a nucleus when they are initially produced. Later, they lose nucleus in order to accommodate more hemoglobin so that they can transport more amount of oxygen.

25. The use of plastics has led to a number of environment-related problems. For this, which one of the following statement is correct?

Correct Answer: (a) They are non-biodegradable.
Solution:Only Statement 1 is correct with reference to the use of plastics it has led to a number of environment problems because plastics are generally non-biodegradable, means they do not break down naturally over time. Instead, they persist in the environment for hundreds or even thousands of years

Statements 2, 3 and 4 are incorrect Plastics can break down into smaller particles called microplastics, which can contaminate water bodies and enter the food chain.

Microplastics have been found in food for human consumption and the average person could be ingesting up to 5 grams of plastic per week. Plastics are synthetic materials made from fossil fuels and do not participate in biochemical synthesis activities.

Plastics can have toxic pollutants that damage the environment and contribute to land, waters and air pollution. Additionally, exposure to plastic waste, especially when burned, can lead to poor air quality and health risks.

26. Microbodies found to be present in plant and animal cells contain

Correct Answer: (b) enzymes
Solution:Microbodies to be found in both plant and animal cells contain enzymes. Many membrane bound minute vesicles called microbodies that contain various enzymes are present in both plant and animal cells.

27. An anti-bacterial enzyme present in saliva and tears is called

Correct Answer: (c) lysozyme
Solution:The antibacterial enzyme presents in saliva and tears are called Lysozyme.

Lysozyme is the enzyme present in tears which prevents eye infections. It is antimicrobial in nature that forms part of the innate immune system. This enzyme causes the lysis of the cell wall of the bacteria. Lysozyme is abundant in secretions including tears, saliva, human milk, and mucus.

28. Which set of vegetables is underground stem or modified stem of a plant?

The central part of the onion, which is often smaller and harder, is the actual stem.

29. Which of the following indicators is/are used to observe the monetary transmission mechanism in the economy?

1. Weighted average lending rate
2. Weighted average domestic term deposit rate
3. 1-year median MCLR
4. SDF rate

Select the correct answer using the codes given below.

Correct Answer: (b) 1, 2 and 3
Solution:Only indicators given in the statements 1, 2 and 3 are used to observe the monetary transmission in the economy. Weighted average lending rate is used to observe the monetary transmission in the economy. The transmission of monetary policy to bank lending rates is higher under the marginal cost of funds-based lending rate (MCLR) regime than under the base rate regime.

The weighted average domestic term deposit rate (WADTDR) is used to observe the monetary trans mission mechanism in the economy. The 1-year median Marginal Cost of Funds Based Lending Rate (MCLR) is used to observe monetary transmission. The MCLR is a lending rate used by banks to determine interest rates for loans. RBI implemented the MCLR in 2016 to improve the transmission of policy rate changes to lending rates.

30. Consider the following statements regarding instruments of monetary policy.
