Question Discussion & Solution

Concept:

In general, each object contains three object associated attributes:

• Object prototype: It is kind of reference/indication to another object from which properties are inherited.
• Object class: It is a kind of string which classifies the type an object.
• Object's extensible flag: It simply specifies that whether some new properties are added to the object

Explanation:

Composting is one of the options for the treatment of solid waste. In the composting process, the organic matter breaks down under bacterial action resulting in the formation of humus like material called compost.

• Vermicomposting: It involves the use of earthworms for composting organic solid waste. It is a resourceful way to recycle your food waste into compost. It takes about 2-3 months.
• Vermicompost (worm manure) is the end-product of the breakdown of organic matter by earthworms. 
• This process of increasing the fertility of soil by earthworms is known as vermicomposting.

Hence, fertilizer produced by the earthworm is called Vermicompost.

Biofertilizers: 

• ​Is a substance that contains living micro-organisms that, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. 
• Biofertilizers add nutrients through the natural processes of Nitrogen fixation.
• Examples: Rhizobium, Azotobacter, Blue-green algae, Azospirilium.

Nitrogen fertilizer:

• Urea, also known as carbamide, is an organic compound with the chemical formula CO(NH₂)₂.
• This amide has two –NH₂ groups joined by a carbonyl functional group.
• Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals.
• The main function of Urea fertilizer is to provide the plants with nitrogen to promote green leafy growth and make the plants look lush.
• Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use.

The correct answer is Butane.

Key Points 

• Liquefied Petroleum Gas (LPG) is a blend of light hydrocarbon compounds.
  • It mainly consists of butane or propane or a mixture of both.
  • At room temperature, both gases are colourless and odourless.
  • It is a mixture of 48% propane, 50% butane, and 2% pentane.

Additional Information

• Water Gas:
  • Water-gas is a mixture of CO and H₂.
  • However, by-products such as char, tar, soot, ash, and condensates are also produced. 
• Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
• Compressed natural gas is a fuel that can be used in place of petrol (gasoline), diesel fuel, and liquefied petroleum gas (LPG).
  • CNG combustion produces fewer undesirable gases than the aforementioned fuels.
  • In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released.

The correct answer is Bundi, Udaipur, Pratapgarh and Banswara

• The correct location of the districts from north to south direction in Rajasthan is Banswara, Pratapgarh, Udaipur and Bundi.

Key Points

• Udaipur:
  • It is sometimes referred ‘Venice of the East.
  • It is bordered by Rajsamand, Chittorgarh & Pratapgarh, Banswara, Dungarpur, Sirohi and Pali.
• Bundi:
  • The district derived its name from a former Meena tribe chief called Bunda Meena. 
  • The district is bordered by Tonk, Sawai-Madhopur, Kota, Chittorgarh, and Bhilwara.
