The reforms introduced by Mikhail Gorbachev in Russia, ‘the Glasnost’ and ‘Perestroika’

Correct option is C) 1950

India has refused to join military pacts set up by America.

The reforms introduced by Mikhail Gorbachev in Russia, ‘the Glasnost’ and ‘Perestroika’ resulted in disbanding of USSR in 1991.

China made a surprise attack on India in 1962.

India made a Panchsheel agreement with China in 1954.

Domination: Rest of the world from 2 blocks, USA and USSR.

Non-alignment implies not belonging to any power bloc but having friendly relations with all the countries. It also means making decisions independently on the basis of merit to solve international problems. Pandit Jawaharlal Nehru was one of the founders of this policy.

Correct option is A) Nasser

Third world: The countries emerging from colonial.

India and U.S.A. are the two largest democracies in the world. During 1947-2001 the relations between the two countries were marked by two opposite features. On one side, there was a spirit of co-operation and friendship between the two countries. But on the other, their relations were strained and conflicting. There has been, however, a marked improvement in the relations between the two countries since 2000 A.D. Both these countries are fighting against terrorism.

The U.S.A. had begun to give massive military aid to Pakistan. This was strongly opposed by India. The lowest point in the Indo-US relations came in 1971 when India signed the Treaty of peace, friendship and co-operation with the USSR. India’s peaceful nuclear explosion on May 18, 1974, at Pokhran was strongly criticised by the US leaders and the people. There has been a marked improvement in the relations between America and India since 2001 A.D. The President of the U.S.A. Barack Obama visited India in January 2015.

Not to join any of the power blocs.

India has made every effort to establish friendly relations with Pakistan but the tension and hatred between the two countries has never ended. The two countries had border disputes, river water distribution disputes and had to make settlement of evacuee property. The dispute about the sharing of river waters between the two countries was settled with the help of the World Bank^ through the Indus Water Treaty in 1960. The settlement of border disputes and the problem of evacuee property have been solved to a great extent. But the Kashmir problem is the bone of contention between the two countries.

5. Loss of viability of seeds show in terminator seed technology of GM crops.

1. Biotechnology is one of the most important applied interdisciplinary sciences of the 21st century. It is the trusted area that enables us to find the beneficial way of life.

2. Biotechnology has wide applications in various sectors like agriculture, medicine,environment and commercial industries.

3. This science has an invaluable outcome like transgenic varieties of plants e.g. transgenic cotton (Bt-cotton), rice, tomato, tobacco, cauliflower, potato and banana.

4. The development of transgenics as pesticide resistant, stress resistant and disease resistant varieties of agricultural crops is the immense outcome of biotechnology.

5. The synthesis of human insulin and blood protein in E.coli and utilized for insulin deficiency disorder in human is a breakthrough in biotech industries in medicine.

6. The synthesis of vaccines, enzymes, antibiotics, dairy products and beverages are the products of biotech industries. 

7. Biochip based biological computer is one of the successes of biotechnology. 

8. Genetic engineering involves genetic manipulation, tissue culture involves aseptic cultivation of totipotent plant cell into plant clones under controlled atmospheric conditions. 

9. Single cell protein from Spirulina is utilized in food industries. 

10. Production of secondary metabolites, biofertilizers, biopesticides and enzymes. 

11. Biomass energy, biofuel, bioremediation and phytoremediation for environmental biotechnology.

If 34A Is divisible by 2 then the remainder should be equal to 0. 

∴ A should be equal to 0, 2, 4, 6, 8. 

∴ 340, 342, 344, 346, 348 are divisible by 2 and gives the remainder ‘0’. 

Among these 346 is divisible by 5 and gives the remainder 1. 

∴ 346 → 6/5(R = 1) 

∴ The value of A = 6.

A) Mukti Bahini

Option : (a) Bangladesh

(d) Karl Ereky

Correct option is (D) 8

Given number 73K is completely divisible by 8.

\(\because\) 736 is completely divisible by 8.

\(\therefore\) K must be 6.

Also, \(736\div8=92\)

Therefore, L must be 2.

Now, K+L = 6+2 = 8

Correct option is  D) 8

Correct option is (a) United Liberation Front of Assam

The Multiples of 181 are 181, 362, 543, 724, 905, 1086 The nearest multiple of 181 to 1024 is 1.086. Hence 62 (1086 – 1024) must be added to 1024 to get a multiple of 181.

Correct option is (a) LTTE

Firstly let us solve for unit’s place,

7 + B = A

And for ten’s place,

3 + A = 9

Which means that A = 6 and B = -1 which is not possible.

So, there should be one carry in ten’s place which means 7 + B >9

3 +A +1 = 9

A = 9-1-3 

= 5

For unit’s place subtracting 10 as one carry is given to ten’s place,

7 + B – 10

= 5

B = 5+10-7 

= 8

∴A = 5 and B = 8

The shuttle vectors are plasmids designed to replicate in cells of two different species. These vectors are created by recombinant techniques. The shuttle vectors can propagate in one host and then move into another host without any extra manipulation. Most of the Eukaryotic vectors are Shuttle Vectors.

Vectors which are suitable for expressing foreign proteins are called expression vectors. This vector consists of signals necessary for transcription and translation of proteins in the host. This helps the host to produce foreign protein in large amounts.

Example: pUC 19.

(a) Both A and R are wrong.

Correct option is  A) 0

(ii) He tried to make several reforms in the field of Indian economy and that of science and technology. 

(iii) He took the lead in solving the issues of the Tamil minority in Sri Lanka. He promoted the idea of a united Sri Lanka with internal autonomy to the Tamil community, but his efforts in this regard proved to be in vain. 

(iv) He faced a lot of criticism in the context of corruption that took place during a defence equipment deal, especially the purchase of longrange canons from a foreign company called Bofors. 

(v) Political corruption became a crucial issue in the general elections that followed and the Congress party was defeated.
