The correct answer is Anaji Chauhan.

• The Anasagar lake was built by  Anaji Chauhan.
  • Ana Sagar Lake is an artificial lake.
  • It is one of Ajmer's most popular lakes and one of India's largest lakes.

Key Points

• Anaji Chauhan
  • The Anasagar lake was built by  Anaji Chauhan.
  • The lake was founded by the grandfather of Prithivi Raj Chauhan, King Anaji Chauhan between 1135 -1150.

Important Points

• The Baradari or pavilions were built by Shahjahan in 1637 and Daulat Bagh Gardens by Jehangir.

Additional Information

• Prithvi Raj Chauhan
  • Prithviraj III, popularly known as Prithviraj Chauhan or Rai Pithora was a king from the Chahamana (Chauhan) dynasty.
  • Prithviraj Raso is purported to be written by his court poet Chand Bardai.  
  • It gives a detailed description of Prithviraj Chauhan.

The correct answer is option 4) i.e. kg-1 m2

CONCEPT:

• Gravitational constant, G: G is a physical constant and therefore is universal in nature and has a constant value everywhere.
  • The value of G does not change with respect to time or place and is equivalent to 6.674 × 10-11 N m2 kg-2
  • The SI unit of G is N m2 kg-2
• Acceleration due to gravity, g: It is the acceleration of a body due to the force exerted from the earth's gravity.
  • It has a constant value of 9.8 m/s² within the surface of Earth.
  • The SI unit of g is m s^-2

EXPLANATION:

The unit of G = N m2 kg-2 = (mass × acceleration)m2 kg-2 = (kg × m/s²)m2 kg-2     (∵ N is the SI unit of force)

The unit of g = m s^-2​

Ratio, \(\frac{G}{g} = \frac{m^3 kg^{-1 }s^{-2 }}{m s^{-2}} =\) kg-1 m2

The correct answer is Fermentation.

Key Points

• Fermentation:
  • The biological process, in which sugar molecules are converted into ethyl alcohol and carbon dioxide with the help of some microbes like yeast and bacteria is called alcohol fermentation.
  • It is an anaerobic process. i.e. it occurs in the absence of oxygen.
  • The process is governed by the enzyme alcohol dehydrogenase
  • Alcoholic fermentation has many uses such as for the production of alcoholic beverages, ethanol fuel, and bread cooking.

Additional Information

• Moulding:
  • ​Moulding is a typical process in which a type of fungus that grows surface of fruits and vegetable.
  • These tubular branches have multiple, genetically identical nuclei, yet form a single organism, known as a colony.
  • In contrast, yeast is a type of fungus that grows as a single cell.
• Nitrogen Fixation:
  • Nitrogen fixation is the chemical process by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle. 
  • Atmospheric nitrogen is fixed by several methods like biological N2 fixation, Industrial N2 fixation & Electrical N2 fixation.
  • It is a necessary process, as the fixed nitrogen is used in the biosynthesis of several organic compounds like amino acids, proteins, nucleic acids, etc.
• Transcription:
  • ​The process of copying genetic information from one strand of DNA into RNA is termed transcription or mRNA synthesis.
  • The process of transcription begins when an enzyme called RNA polymerase attaches to the template DNA strand and begins to catalyze the production of complementary RNA.
  • It is completed in three steps Initiation, Elongation & Termination.

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
