• 'Public Accounts Committee' is the committee to audit the expenses of the Government of India.
• In this committee, it consists of 22 members, out of which 15 members are from Lok Sabha and 7 are from Rajya Sabha. Therefore statement 1 is wrong.
• Its members are elected by a single transferable vote system.
• The Chairman of the Public Accounts Committee is a member of the opposition party.
• This committee examines the annual reports of the CAG, which are presented to the Parliament by the President. Therefore statement 3 is correct.
• The committee examines public expenditure not only from a legal and formal point of view to discover technical irregularities but also from the point of view of the economy, prudence, wisdom and propriety. Therefore statement 2 is correct.

Ryotwari system:

• The factors varied from farm to farm and region to region in both parts of India.
• Moreover, they are not a convincing argument for decentralization of the land revenue system in the South.
• Ryotwari was tried first on a small scale by Captain Alexander Read in some of the areas that were taken over by the Company after the wars with Tipu Sultan.
• Subsequently developed by Thomas Munro, this system was gradually extended all over south India.
• Read and Munro felt that in the south there were no traditional zamindars.
• The settlement, they argued, had to be made directly with the cultivators (ryots) who had tilled the land for generations.
• Their fields had to be carefully and separately surveyed before the revenue assessment was made.
• Munro thought that the British should act as paternal father figures protecting the ryots under their charge.

Protozoa mainly feed on bacteria, but they also eat other protozoa, and sometimes fungi. Therefore statement 1 is correct.

Some protozoa absorb food through their cell tissues.

All protozoa digest their food in stomach-like compartments.

As they digest, they make and give off nitrogen, which is an element that plants and other higher creatures can use. Therefore statement 2 is correct.

Most protozoa do us no harm. But there are a few that cause diseases.

One type of amoeba can live in human intestines.

• It feeds on red blood cells and causes a disease known as dysentery.

Another species of protozoa can sicken hundreds of thousands of people when it gets into the tap water.

• Perhaps the best-known deadly protozoa cause malaria. Therefore statement 3 is correct.

q1zFor Cotton, light rainfall is needed. For Jute high rainfall and temperature is needed.  

Wheat requires moderate temperature and rainfall during growing season and bright sunshine at the time of harvest.

• It thrives best in well-drained loamy soil. Wheat is grown extensively in USA, Canada, Argentina, Russia, Ukraine, Australia and India. In India it is grown in winter.

Maize requires moderate temperature, rainfall and lots of sunshine. It needs well-drained fertile soils.

• Maize is grown in North America, Brazil, China, Russia, Canada, India, and Mexico.

• The Science and Engineering Research Board (SERB) has launched a new scheme called ‘Accelerate Vigyan’ to provide a single platform for research internships, capacity-building programs and workshops across the country. Therefore statement 1 is correct.
• The primary objective of this inter-ministerial scheme is to encourage high-end scientific research and prepare scientific manpower, which can lead to research careers and a knowledge-based economy. Therefore statement 2 is correct.
• Accelerate Vigyan will initiate and strengthen mechanisms for identifying research potential, mentoring, training and hands-on workshop on a national scale.
• The scheme is subdivided into two components: ‘ABHYAAS’ and ‘SAMMOHAN’.

Microeconomic policies are pursued by the State itself or statutory bodies like the Reserve Bank of India (RBI), Securities and Exchange Board of India (SEBI) and similar institutions. Typically, each such body will have one or more public goals to pursue as defined by law or the Constitution of India itself. These goals are not those of individual economic agents maximising their private profit or welfare. Thus the macroeconomic agents are basically different from the individual decision-makers.

It is one of the major festivals celebrated by the Chakhesang tribe, predominantly by the Poumai Chakhesang from the Razeba area.

• For the Poumai community in Manipur, Thuni is a premier festival of new harvest.
• It is celebrated from January 5th every year and continues for several days.
• Most importantly, Thuni is a festival of equity when both the rich and the poor; the old and the young share from the same barrel of rice beer and eat the same food.

• Today 21 countries, with surface areas from 2 km² to 2.4 million km², have coastlines on the Mediterranean Sea.
• They are Albania, Algeria, Bosnia and Herzegovina, Croatia, Cyprus, Egypt, France, Greece, Israel, Italy, Lebanon, Libya, Malta, Monaco, Montenegro, Morocco, Slovenia, Spain, Syria, Tunisia, and Turkey.

Mediterranean Sea:

• It separates Europe from Africa, Strait of Gibraltar.
• It connects to the Atlantic Ocean.
• It has often been called the incubator of Western civilization.
• This ancient "sea between the lands" occupies a deep, elongated, and almost landlocked irregular depression lying between latitudes and longitudes.
• It includes the Sea of Marmara, occupies an area of approximately 970000 square miles.
• To the northeast, it is connected with the Black Sea through the Dardanelles, the Sea of Marmara, and the strait of Bosporus.
• To the southeast, it is connected with the Red Sea by the Suez Canal.

• The eye lens focuses light on the back of the eye, on a layer called the retina.
• The retina contains several nerve cells.
• Sensations felt by the nerve cells are then transmitted to the brain through the optic nerve.
• At the junction of the optic nerve and the retina, there are no sensory cells, so no vision is possible at that spot.
• This is called the blind spot.

DNA stands for deoxyribonucleic acid, while RNA is ribonucleic acid. Although DNA and RNA both carry genetic information, there are quite a few differences between them.

This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences.

• DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring.
• DNA is a double-stranded molecule, while RNA is a singlestranded molecule.
• DNA is stable under alkaline conditions, while RNA is not stable.
• DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.
• DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.
