Question Discussion & Solution

The correct answer is Zila Parishad → Panchayat Samiti → Village Panchayat.

Key Points

• Panchayati Raj
  • Panchayati Raj is the system of local self-government of villages in rural India as opposed to urban and suburban municipalities.
  • It consists of the Panchayati Raj Institutions (PRIs) through which the self-government of villages is realized.
  • They are tasked with "economic development, strengthening social justice and implementation of Central and State Government Schemes including those 29 subjects listed in the Eleventh Schedule."
  • ​Part IX of the Indian Constitution is the section of the Constitution relating to the Panchayats.
  • It stipulates that in states or Union Territories with more than two million inhabitants there are three levels of PRIs:
    • Zilla Parishad at the District Level
    • Panchayat Samiti at the Block Level
    • Gram/Village Panchayat at the Village Level

 Additional Information

• The Panchayat Raj system was first adopted by the state of Rajasthan in Nagaur district on 2 Oct 1959 but first started by Andhra Pradesh.
• During the 1950s and 60s, other state governments adopted this system as laws were passed to establish panchayats in various states.
• The modern Panchayati Raj system was introduced in India by the 73rd constitutional amendment in 1993.

The correct answer is Angiosperm.

Key Points

• Angiosperms are also known as Angiospermae or Magnoliophyta.
  • They are flowering and seed-producing plants.
  • It consists of 64 orders, 416 families, approximately 13,000 known genera, and 3,00,000 known species.
  • Their seeds develop in the ovaries of flowers and are surrounded by a protective fruit.
  • Examples of angiosperms are fruits, vegetables, grains, and flowers.
  • Angiosperms are classified as Monocotyledons (monocots) and Dicotyledons (dicots) where monocots are flowering plants whose seeds contain only one embryonic leaf or cotyledon and dicots are flowering plants whose seeds contain two embryonic leaves or cotyledons.

Additional Information

• Thallophyta
  • The plant body is not differentiated from roots, stems, and leaves.
  • They are commonly called algae.
• Bryophyta
  • These are small terrestrial plants.
  • They show differentiation in the body design, with stem, leaf-like structures, and root-like structures.

Concept:

• The laws dealing with ideal gases naturally called ideal gas laws, and the laws determined in the seventeenth century by Boyle's observational work and in the eighteenth century by Charles.
• The Boyles Law states that the gas pressure is inversely proportional to the gas volume for a given mass of gas stored at a constant temperature.
• Charles Law states that the gas volume is directly proportional to the gas temperature for a given fixed mass of gas stored at a constant pressure. 
• An ideal gas is a gas that follows the equation:

PV = nRT at all temperatures and pressure, where P = Pressure of the ideal gas. V = Volume of the ideal gas n = Amount of ideal gas measured in terms of moles 

R = Universal gas constant T = Temperature

Mole Concept -

•  The quantity one mole of a substance signifies 6.022 × 1023 number of particles of that substance which may be atoms, molecules, or ions.
• The quantity is a universal constant like Dozen, Gross, etc., and is known as Avogadro number, denoted by NA. after the scientist Amedeo Avogadro.
• Examples- In one mole of H2, there are 6.022 × 1023 molecules of hydrogen, and the number of atoms is 2 × 6.022 × 1023, as one molecule of hydrogen contains two-atom each.
• The mass of one mole of a substance is called its Molar Mass (M) or Atomic mass expressed in grams.
• The volume occupied by a mole of gas is 22.4 L at NTP, called its Molar Volume.
• The no. of moles (n) is calculated as =

The number of particles / Avogadro’s number.

To summarise, we can say, 

Calculation:

• The molar mass of 1 mole of H₂SO₄ is =

2 × 1 + 32 + 4 × 16 = 98g

• The molar mass of 1 mole of Silver, Ag is its molecular mass 108g.
• The molar mass of CO₂ is = 12 + 2× 16 = 44g.
• 44g of CO₂ means one mole.
• 1 mole of Oxygen weighs 16 + 16 = 32g.
• Hence, the highest mass is of 1 mole of Ag.
