Question Discussion & Solution

The correct answer is Aravali.

• Aravali range forms the main water area for Rajasthan.

Key Points

• Aravali range​
  • The Aravallis of Northwestern India, one of the oldest fold mountains of the world, now form residual mountains with an elevation of 300m. to 900m.
  • They stretch for a distance of 800 km from Himmatnagar in Gujarat to Delhi, spanning Haryana, Rajasthan, Gujarat, and Delhi, the 692 kilometres (km).
  • The Aravallis act as a barrier between the fertile plains in the east and the sandy desert in the west.
  • Historically, it is said that the Aravalli range checked the spread of the Thar desert towards the Indo-Gangetic plains, serving as a catchment of rivers and plains.
  • Thus Aravali range forms the main water area for Rajasthan.

​Additional Information

•  Aravali range formation
  • ​These are fold mountains of which rocks are formed primarily of the folded crust when two convergent plates move towards each other by the process called orogenic movement.
  • The Aravallis date back to millions of years when a pre-Indian sub-continent collided with the mainland Eurasian Plate.
  • Carbon dating has shown that copper and other metals mined in the ranges date back to at least the 5th century BC.

CONCEPT:

• Power is the ability to bend light and it is equal to the reciprocal of the focal length of the lens/mirror in meters.

Power (P) = 1/f

Where f is the focal length of the lens/mirror.

EXPLANATION:

As explained above, Dioptre is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres.

And since the S.I unit of the focal length is the meter (m).

So the S.I unit of power = 1/(SI unit of focal length) = m-1 = Dioptre (D).

1 m-1 = 1 D

In a certain code language, 'BENJAMIN' is written as 'NIMAJNEB'. First letter of the word moves last and second letter of the word moves second last place and so on.

Similarly, 'POVERTY' written in that code language as 

POVERTY is written as YTREVOP.

Hence, "YTREVOP" is the correct answer.

Explanation:

• Parenchyma, Sclerenchyma, and Collenchyma are the Simple Permanent Plant tissues.
• Xylem and Phloem are the Complex Permanent Plant tissue.
• Sclerenchyma: supporting tissue in higher plants.
• Parenchyma: makes up most of the cells within leaves, flowers, and fruits.
• Collenchyma: provides support, structure, tensile strength, and flexibility which helps the plant to bend.
• Xylem:
  • It is plant tissue that transports food water and other dissolved minerals from roots to other parts of the plant.
• Phloem:
  • The main function of the phloem is to transport food materials from the leaf to other parts of the plant.
