21. In vertebrates, smooth endoplasmic reticulum in cells of which organ plays a crucial role in detoxification of toxic compounds?

Correct Answer: (d) Liver
Solution:Smooth endoplasmic reticulum is the cell organelle which plays a crucial role in detoxifying poisons and drugs from the liver cells of vertebrate.

22. The rate of an enzyme catalyzed reaction depends:

Correct Answer: (a) upon substrate concentration, temperature and pH
Solution:The rate of an enzyme catalysed reaction increases with the increase in temperature up to a maximum and then falls. Enzyme activity is also affected by pH.

The substrate concentration also influences enzyme activity. As the substrate concentration increases the rate of reaction also increases. This is because the more substrate molecules will interact with enzyme molecules; the more products will be formed.

23. Both starch and glycogen are made up of glucose, however:

Correct Answer: (b) glycogen is made in animal cells, but starch is made in plant cells.
Solution:The carbohydrates are stored in animal body as glycogen. It is also known as animal starch because its structure is similar to amylopectin and is rather more highly branched. Carbohydrates are used as storage molecules as starch in plants and glycogen in animals.

24. In some viral infections, number of platelets are reduced quickly. Platelets are essential because:

Correct Answer: (d) platelets have a role in blood clotting.
Solution:Platelets also called thrombocytes, are cell fragments produced from megakaryocytes (special cells in the bone marrow). Blood normally contains 1,500,00-3,500,00 platelets mm-3. Platelets can release a variety of substances most of which are involved in the coagulation or clotting of blood. A reduction in their number can lead to clotting disorders which will lead to excessive loss of blood from the body.

25. The focus of the Second Five year plan was:

Correct Answer: (b) rapid industrialization with emphasis on the development of basic and heavy industries.
Solution:The Second Five Year Plan covers the period from April 1956 through March 1961. The second five-year plan's driving force was P.C. Mahalanobis. Its objective was Rapid industrialization, particularly basic and heavy industries such as iron and steel, heavy chemicals, fertilizers, heavy engineering and machine building industry.

26. An Indian business person buys shares in a British car company. This transaction will be reflected in:

Correct Answer: (b) Balance of Payments, but not in Balance in Trade.
Solution:The balance of payments (BoP) record the transactions in goods, services and assets between residents of a country with the rest of the world for a specified time period typically a year. There are two main accounts in the BoP-the current account and the capital account. The capital account records all international purchases and sales of assets such as money, stocks, bonds, etc. Balance of trade records the volume of goods and services imported as well as exported by a country to other countries.

27. Which of the following are High Frequency Indicators of the Indian economy?

1. Power Consumption

2. IIP General Index

3. 10 year G-sec yield

Select the correct answer using the code below.

Correct Answer: (d) 1, 2 and 3
Solution:High Frequency Indicators (HFIs) (New Addition) Set 1- Monthly HFIs (Power Consumption, E-way bills (Volume), GST, CPI, CPI Food, CPI Core, Rail Freight Traffic, Port Cargo Traffic) Set 2- Monthly HFIs (Domestic Air Traffic, UPI (Volume), IIP General Index, 8-Core Industries, Domestic Tractor Sales, Domestic Passenger Vehicles Sales, Two Three Vehicle Sales) Set 3- Monthly HFIs (10 year G-Sec yield, 10 year AAA Corporate Bond yield, Average Crude Oil Price (Brent, Dubai, WTI), Indian Crude Oil Basket Price, Baltic Dry Index, Forex Reserves, Sensex, Nifty, Nifty VIX) Set 4- Monthly HFIs (Exchange Rate, Net purchase (+)/sale (-) of US dollar, Fuel Consumption, M3, Currency in Circulation, Merchandise Exports, Merchandise Imports) Set 5- Monthly HFIs (New EPF Subscribers, Members exited, Exited members who rejoined and resubscribed, Net payroll addition). Reference: Budget 2023.

28. Suppose an Indian citizen makes an investment abroad and earns a positive return on her investment. Which of the following is correct?

Correct Answer: (b) Her income is part of India's national income, but not part of India's GDP.
Solution:If we sum the gross value added of all the firms of the economy in a year, we get a measure of the value of aggregate amount of goods and services produced by the economy in a year. Thus GDP = Sum total of gross value added of all the firms in the economy. GNP(Gross National Product) = GDP + Net factor income from abroad. NNP = GNP - Depreciation. NNP at factor cost = National Income (NI)

29. If the Cash Reserve Ratio is lowered by the RBI, supply of money in the economy will:

Correct Answer: (c) increase.
Solution:Cash Reserve Ratio (CRR) = Percentage of deposits which a bank must keep as cash reserves with the bank. Thus if CRR is lowered, than banks will have more money to lend. Thus the supply of money will increase in the economy.

30. Which one of the following is the main cause of the acid rains?

Correct Answer: (b) The burning of fossil fuels releases oxides of carbon, nitrogen and sulphur in the atmosphere.
Solution:Acid rain is a by-product of a variety of human activities that emit the oxides of sulphur and nitrogen in the atmosphere. Burning of fossil fuels (which + contain sulphur and nitrogenous matter) such as coal and oil in power stations and furnaces or petrol and diesel in motor engines produce sulphur dioxide and nitrogen oxides.

SOâ‚‚ and NO2 after oxidation and reaction with water are major contributors to acid rain, because polluted air usually contains particulate matter that catalyses the oxidation.
