Solution: d)
All are correct.
Acquired immunity, on the other hand, is pathogen specific. It is characterised by memory. This means that our body when it encounters a pathogen for the first time produces a response called primary response which is of low intensity. Subsequent encounter with the same pathogen elicits a highly intensified secondary or anamnestic response. This is ascribed to the fact that our body appears to have memory of the first encounter.
The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, B-Lymphocytes and TLymphocytes. The B-lymphocytes produce an army of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies. The T-cells themselves do not secrete antibodies but help B cells produce them. Each antibody molecule has four peptide chains, two small called light chains and two longer called heavy chains. Hence, an antibody is represented as H2L2.
Different types of antibodies are produced in our body. IgA, IgM, IgE, IgG are some of them. Because these antibodies are found in the blood, the response is also called as humoral immune response. This is one of the two types of our acquired immune response – antibody mediated. The second type is called cell-mediated immune response or cell-mediated immunity (CMI). The T-lymphocytes mediate CMI. Very often, when some human organs like heart, eye, liver, kidney fail to function satisfactorily, transplatation is the only remedy to enable the patient to live a normal life. Then a search begins – to find a suitable donor Grafts from just any source – an animal, another primate, or any human beings cannot be made since the grafts would be rejected sooner or later. Tissue matching, blood group matching are essential before undertaking any graft/transplant and even after this the patient has to take immuno–suppresants all his/her life. The body is able to differentiate ‘self ’ and ‘nonself’ and the cell-mediated immune response is responsible for the graft rejection.

Solution (c)
Area under Permanent Pastures and Grazing Lands : Most of this type land is owned by the village ‘Panchayat’ or the Government. Only a small proportion of this land is privately owned. The land owned by the village panchayat comes under ‘Common Property Resources’. Culturable Waste-Land: Any land which is left fallow (uncultivated) for more than five years is included in this category. It can be brought under cultivation after improving it through reclamation practices. Current Fallow: This is the land which is left without cultivation for one or less than one agricultural year. Fallowing is a cultural practice adopted for giving the land rest. The land recoups the lost fertility through natural processes. Net Area Sown: The physical extent of land on which crops are sown and harvested is known as net sown area

Solution: c)
Whips
In the parliamentary form of Government, a party has its own internal organisation inside Parliament and is served by a number of officials known as the Whips, chosen from members of the party itself. The main function of the Whips is to keep members of their party within sound of the Division Bell whenever any important business is under consideration in the House.
During sessions, the Whips of different parties send to their supporters periodic notices, also sometimes called ‘Whips’, apprising them when important Divisions are expected, telling them the hour when a vote will probably take place, and requesting them to be in attendance at that time. Realizing the vital role played by the Chief Whips and leaders of parties and groups in Parliament as important party functionaries, an Act namely the Leaders and Chief Whips of Recognized Parties and Groups in Parliament (Facilities) Act {Act 5 of 1999) was passed during the Twelfth Lok Sabha. The Act inter alia provides additional Secretarial assistance and telephone facilities to the Leaders and Chief Whips.
Government Chief Whip: The Chief Whip of the Government Party in the Lok Sabha is the Minister of Parliamentary Affairs. In the Rajya Sabha, the Minister of State for Parliamentary Affairs holds this position. The Chief Whip is directly responsible to the Leader of the House. It is part of his duties to advise the Government on parliamentary business and to maintain a close liaison with the Ministers in regard to parliamentary business affecting their Departments. The Chief Whip is assisted by one or two Ministers of State and at times by Deputy Ministers also

Solution: d

Solution: c)
The Rowlatt Act passed by the Imperial Legislative Council in London on 10 March 1919, indefinitely extending “emergency measures” (of the Defence of India Regulations Act) enacted during the First World War in order to control public unrest and root out conspiracy, in India. Passed on the recommendations of the Rowlatt Committee, named after its president, British judge Sir Sidney Rowlatt, this act effectively authorized the government to imprison for up to two years, without trial, any person suspected of terrorism living in the Raj and gave the imperial authorities power to deal with revolutionary activities. The unpopular legislation provided for stricter control of the press, arrests without warrant, indefinite detention without trial, and juryless in camera trials for proscribed political acts. The accused was denied the right to know the accusers and the evidence used in the trial.[1] Those convicted were required to deposit securities upon release and were prohibited from taking part in any political, educational, or religious activities.[1] Mohandas Karamchand Gandhi, among other Indian leaders, was extremely critical of the Act and argued that not everyone should get punishment in response to isolated political crimes. The Act annoyed many Indian leaders and the public, which caused the government to implement repressive measures. Gandhi and others found that constitutional opposition to the measure was fruitless, so on April 6, a “hartal” was organised where Indians would suspend all business and fast as a sign of their opposition. This event is known as theRowlatt satyagraha. Gandhiji named rowlatt act as “black act”. However, the success of the hartal in Delhi, on 30 March, was overshadowed by tensions running high, which resulted in rioting in thePunjab and other provinces. Deciding that Indians were not ready to make a stand consistent with the principle of ahimsa (non-violence), an integral part of satyagraha, Gandhi suspended the resistance. The Rowlatt Act came into effect in March 1919. In the Punjab the protest movement was very strong, and on 10 April, two leaders of the congress, Dr. Satya Pal and Dr. Saifuddin Kitchlew, were arrested and taken to an unknown place. Army was called in Punjab and on 13 April people from neighbouring villages gathered for Baisakhi Day celebrations in Amritsar, which led to the infamous Jallianwala Bagh massacre of 1919.[2][3] Accepting the report of the Repressive Laws Committee, the Government of India repealed the Rowlatt Act, the Press Act and twenty-two other laws in March 1922

Among the significant causes of Non-Cooperation movement were colonial oppression, exemplified by the Rowlatt Act and Jallianwala Bagh massacre, economic hardships to the common man due to a large chunk of Indian wealth being exported to Britain, ruin of Indian artisans due to British factory-made goods replacing handmade goods, and popular resentment with the British over Indian soldiers dying in World War I while fighting as part of the British Army, in battles that otherwise had nothing to do with India

Solution: c)
Agricultural technologies While the prevalence of agriculture is indicated by finds of grain, it is more difficult to reconstruct actual agricultural practices. Were seeds broadcast (scattered) on ploughed lands?
Representations on seals and terracotta sculpture indicate that the bull was known, and archaeologists extrapolate from this that oxen were used for ploughing. Moreover, terracotta models of the plough have been found at sites in
Cholistan and at Banawali (Haryana). Archaeologists have also found evidence of a ploughed field at Kalibangan (Rajasthan), associated with Early Harappan levels.
The field had two sets of furrows at right angles to each other, suggesting that two different crops were grown together. Archaeologists have also tried to identify the tools used for harvesting. Did the Harappans use stone blades set in wooden handles or did they use metal tools?
Most Harappan sites are located in semi-arid lands, where irrigation was probably required for agriculture. Traces of canals have been found at the Harappan site of Shortughai in Afghanistan, but not in Punjab or Sind. It is possible that ancient canals silted up long ago. It is also likely that water drawn from wells was used for irrigation. Besides, water reservoirs found in Dholavira (Gujarat) may have been used to store water for agriculture

Solution: b)
Separation and isolation of DNA fragments : The cutting of DNA by restriction endonucleases results in the fragmentes of DNA. These fragments can be separated by a technique known as gel electrophoresis.
Since DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix. Nowadays the most commonly used matrix is agarose which is a natural polymer extracted from sea weeds.
The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.

Solution: c

Simple Interest = Principal Amount * Time * Rate of Interest / 100

Here, Interest = 10000 * 10 * x/100 = 1000x

Amount received after 10 years = 10000 + 1000x

This is reinvested again,

Interest = (10000 + 1000x) * 10 * r/100 = (10 + x) 100x

Final amount received = Principal + Interest = (10000 + 1000x) + 100x(10+x) = 22500

i.e x^2 + 20x – 125 = 0

x = 5

L.C.M of 6, 14 and 21 is 42

Least number of biscuits = 42 + 3 = 45

Solution: b

Total number of years from 1985 to 2086 = 101

Leap years = 25

1985 is not a leap year because it cannot be divided by 400

Therefore, number of odd days in the remainder of 101 + 25 / 7 = 0

So, it is Tuesday again
