Question Discussion & Solution

Today most countries in the world have a Constitution. While all democratic countries are likely to have a Constitution, it is not necessary that all countries that have a Constitution are democratic.

Important Points

Key features of the Indian Constitution:

• Federalism:
  • This refers to the existence of more than one level of government in the country.
  • In India, we have governments at the state level, at the centre and Panchayati Raj at the village level.
  • The Constitution contains lists that detail the issues that each tier of government can make laws on.
  • In addition, the Constitution also specifies where each tier of government can get the money from, for the work that it does.
  • All persons in India are governed by laws and policies made by each of these levels of government.
• Parliamentary form of government:
  • The people of India have a direct role in electing their representatives. Also, every citizen of the country, irrespective of his/her social background, can contest in elections.
• Separation of powers:
  • There are 3 organs of government:
    • The legislature: refers to elected representatives by the people.
    • The executive: is a smaller group of people who are responsible for implementing laws and running the government.
    • The judiciary: refers to the system of courts in India.
  • Each organ mentioned above acts as a check on the other organs of government. This ensures the balance of power between all three.
• Fundamental rights:
  • The constitution guarantees the rights of individuals against the State as well as against other individuals. It also guarantees the rights of minorities against the majority.
  • The Fundamental Rights in the Indian Constitution include:
    • Right to Equality
    • Right to Freedom
    • Right against Exploitation
    • Right to Freedom of Religion
    • Cultural and Educational Rights
    • Right to Constitutional Remedies

From the above, we can conclude that the Presidential form of government is not a feature of the Indian constitution.

​The correct answer is Jain temples.

• Mewa Nagar, a town in Barmer district of Rajasthan is famous for Jain temples.

​Key Points

• Mewa Nagar, Barmer district
  • The old name of this village was Veerampur and it is said that it was built in the 12th or 13th century. 
  • There are 3 Jain temples and a Vishnu temple here:
    • The largest and oldest temple here is of Nakoda Parshwanath. 
    • Other Jain temples are dedicated to Rishbhadeva and Shantinath. 

Additional Information

• Meva Nagar is built on a hillside. 
• This hill is known as the town's goats and it is located at a distance of 8 km from Balotar Nagar.
• There are many historical inscriptions here. 
• A fair is held here every year in the month of Pus.

The input device is any hardware used by a human operator or other systems to communicate with a computer. 

Input Device: A piece of equipment/hardware that helps us enter data into a computer is called an input device. 

Examples of an Input device:

Keyboard, mouse, scanner, joystick, etc.

Additional Information

The correct answer is ​Red and yellow soil.

Key Points

• Red and Yellow Soil:
  • Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern part of the Deccan Plateau. Hence option 1 is correct.
  • Along the piedmont zone of the Western Ghat, a long stretch of area is occupied by red loamy soil.
  • Yellow and red soils are also found in parts of Odisha and Chhattisgarh and in the southern parts of the middle Ganga plain.
  • The soil develops a reddish colour due to a wide diffusion of iron in crystalline and metamorphic rocks.
  • It looks yellow when it occurs in a hydrated form.
  • The fine-grained red and yellow soils are normally fertile, whereas coarse-grained soils found in dry upland areas are of poor infertility.
  • They are generally poor in nitrogen, phosphorous and humus.

Concept:

The nucleus of the Cell

• The cell is the basic building block of all living beings. 
• The nucleus is the special structure located generally at the center of the cell. 
• The nuclear membrane separates the cytoplasm from the nucleus. 
• The nucleus contains a central part called nucleolus and chromosomes. 
• Chromosomes and nucleolus coexist in the nucleus. Chromosomes are not present in the nucleolus.

Chromosomes and Genes

• Chromosomes carry genes and help in the inheritance or transfer of characters from the parents to their children. 
• The chromosomes can be seen only when the cell divides.
• The credit for the discovery of chromosomes goes to Strasburger as he first described the chromosome structure seen in the nucleus during cell division.
• Usually, chromosomes are rod-shaped, elongated, or dot-like in shape with sizes varying from 0.5 to 32 micrometer.
• In humans, 23pairs of chromosomes are found i.e. 46 in numbers.

Conclusion:

• Chromosomes are present in the nucleus of the cell. So, all the given options are wrong. 
• The correct option is None of these.

Additional Information

• The cell membrane is also known as the plasma membrane. 
  • It is a porous structure that allows the exit and entry of certain materials according to its requirement. 
  • This is the major function of the cell membrane. 
• The cytoplasm is between the cell and the nucleus.
  • Cell organelles like mitochondria, Golgi bodies, ribosomes, etc. are present in the cytoplasm. 
  • Mitochondria is called the powerhouse of cells and is responsible for cellular respiration. 
  • vacuole is open space between cell which is used for storing food. 
• Plastids are double-membrane organelles found in the plant cell. They contain pigments that help the plant in photosynthesis.
