31. Match List-I with List-II and select the correct answer using the code given below the Lists:

List-I (Tropical Cyclone)List-II (Location)
A. Cyclones1. USA
B. Hurricanes2. East Asia
C. Typhoons3. Australia
D. Willy-willies4. India

 

Code:ABCD
(a)4213
(b)4123
(c)3124
(d)3214
Correct Answer: (b)
Solution:Cyclones occur mostly in India. They occur in the month of May-June and October-November. It is a system of winds rotating counter clockwise in the Northern Hemisphere around a low-pressure centre. Hurricanes occur mostly in the USA.

It is a type of storm, which forms over tropical or subtropical waters. Typhoons occur mostly in East Asia. Willy-willies occur mostly in Australia. It is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. Therefore, the correct option is (b).

32. Match List-I with List-II and select the correct answer using the code given below the Lists:

List-I (Element)List-II (Application)
A. Isotope of Uranium1. Treatment of cancer
B. Isotope of Cobalt2. Treatment of goitre
C. Isotope of Iodine3. Treatment of secondary cancer
D. Isotope of Radium4. Nuclear fuel

 

Code:ABCD
(a)3214
(b)4213
(c)4123
(d)3124
Correct Answer: (c)
Solution:The isotope of radium is used to treat secondary cancer. Iodine (Iodine-131) is used in the treatment of goitre. It reduces the size of the goitre, but eventually may also cause an underactive thyroid gland.

The gamma rays from the radioisotope Cobalt (cobalt-60) is used to treat cancer. Uranium (U-235) is used as a fuel in nuclear reactors. Therefore, the correct option is (c).

33. Hemocyanin is an oxygen-transport metalloprotein present in some invertebrate animals. This protein contains:

Correct Answer: (b) two copper atoms
Solution:Hemocyanins contain two copper atoms that reversibly bind a single oxygen molecule. Hemocyanins are respiratory proteins that use copper-binding sites to bind and transport oxygen in a variety of arthropods and molluscs.

Hemocyanins, such as haemoglobin, are multi-subunit molecules where each subunit (arthropods) or functional unit of a subunit (mollusks) binds oxygen. Unlike the haemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph. Therefore, option (b) is correct.

34. ' A' B' and 'C' started their independent businesses with equal amounts of capital. During the first year 'A' made 10% profit, 'B' incurred 10% loss and 'C' made a profit of 5%. In the second year ' A' incurred 20% loss, ' B' made profit of 20% and 'C' made profit of 5%. Which of the following is FALSE at the end of second year ?

Correct Answer: (c) 'B' is the richest
Solution:
1st year2nd year
A10% profit20% loss
B10% loss20% profit
C5% profit5% profit

Let A, B and C started their business with equal amount of 100.

Then, at the end of 2nd year :

A → 100 × 110/100 × 80/100 = 88

B → 100 × 90/100 × 120/100 = 108

C → 100 × 105/100 × 105/100 = 110.05

Clearly, we can see that option (c) is false.

35. At what time between 2 and 3 will the hour and minute hands of a clock be 12 minutes divisions apart?

Correct Answer: (c) 24 minutes past 2
Solution:Minute hand will show = [(5 x 2) +12] × 12/11

Minute hand will show = 22 × 12/11

Minute hand will show = 24 minutes

The time shown on the clock will be 24 minutes past 2.

36. Which of the following statements with regard to the continental shelf is NOT correct?

Correct Answer: (c) They have abrupt falls towards the continental slopes
Solution:A continental shelf is defined as a portion of a continent that is submerged under an area of relatively shallow water calledthe shelf sea. They are highly sedimented. Along with parts of the U.S. state of California, for example, the continental shelf extends less than a kilometre.

But, along the northern coast of Siberia, the shelf extends about 1,290 kilometres. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an insular shelf. Therefore, option (c) is correct.

37. Arrange the following National Parks of India from North to South direction:

1. Indravati National Park

2. Nagarhole National Park

3. Corbett National Park

4. Madhav National Park

Select the correct answer using the code given below :

Correct Answer: (c) 3, 4, 1, 2
Solution:National Parks from North to South direction are as follows:
  • Corbett National Park is located in Uttarakhand. It is known for its Bengal tigers. Animals, including tigers, leopards and wild elephants, roam the Dhikala zone.
  • Madhav National Park is located in Gwalior, MP. The Park was the hunting ground of Mughal emperors and Maharaja of Gwalior.
  • Indravati National Park is located in Chhattisgarh. It is home to one of the last populations of rare wild buffalo.
  • Nagarhole National Park is located in Karnataka. It is known for its tiger sightings.

Therefore, option (c) is correct.

38. Match List I with List II and select the correct answer using the code given below the Lists:

List-I (Scientist)List-II (Area of study)
A. J.D. Watson1. Microbiology
B. Louis pasteur2. Taxonomy
C. Carl Linnacus3. Molecular Biology
D. Charles Darwin4. Evolution

 

Code:ABCD
(a)4213
(b)4123
(c)3124
(d)3214
Correct Answer: (c)
Solution:J.D. Watson is a scientist in molecular biology. He was an American molecular biologist, who was best known for the discovery of the structure of DNA. Loius Pasteur is a scientist in microbiology.

He is best known for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization. Carl Linnacus was a Swedish botanist who is known as the "father of modern taxonomy". Charles Darwin was an English naturalist who is best known for the theory of evolution. Therefore, the correct option is (c).

39. Which one of the following statements is correct?

Correct Answer: (b) Iron sulphate and zinc sulphate crystals have same number of water of crystallization
Solution:Both Iron Sulphate (FeSO4 7H₂O₄) and Zinc Sulphate crystals (ZnSO4. 7H₂O) have the same number of water of crystallization, i.e.,7. It refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation. The hydrated form of iron sulphate is used medically to treat iron deficiency, and also for industrial applications. It was historically known as "white vitriol". Zinc sulfate and its hydrates are colourless solids. Therefore, option (b) is correct.

40. If in a certain language NEOMAN is coded as OGRQFT, then ZKCLUP is the code of:

Correct Answer: (b) YIZHPJ
Solution:
