Question Discussion & Solution

Explanation:

• Bacteria are the sole members of the Kingdom Monera. They are the most abundant micro-organisms.
• On the basis of origin, bacteria can be divided into two types - Archaebacteria & Eubacteria

Archaebacteria:

• These bacteria are special since they live in some of the harshest habitats such as extreme salty areas (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens).
• Archaebacteria differ from other bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions.
• For example - Methanogens are present in the gut of several ruminant animals such as cows and buffaloes and they are responsible for the production of methane (biogas) from the dung of these animals.

Additional Information 

Eubacteria:

• There are thousands of different eubacteria or ‘true bacteria’.
• They are characterised by the presence of a rigid cell wall, and if motile, a flagellum.
• The Eubacteria can be both autotrophic & heterotrophic.

The correct answer is Velocity, time, and acceleration.

The first equation of motion gives the relation between initial velocity, final velocity, acceleration, and time.

• First equation of motion is given as v = u + at
  • Where, v = final velocity
  • u = initial velocity
  • a = acceleration
  • t = time taken

• The first equation of motion gives the value of velocity acquired by the body at any particular point of time t.
• The second equation of motion is given as s = ut + ½at²
• It gives the value of distance (s) traveled by a body at a given time t.
• Third equation of motion is given as v² = u² + 2as
• This equation gives the velocity of the body in traveling the distance s.

Hence the code for change out is “reshsab”.

The correct answer is in 1957.

• Rajasthan State Sports Council was established in 1957.

Key Points

• Rajasthan State Sports Council is the premier body in Rajasthan at the State level which looks after the development of sports activities and providing coaching to the state players.
