Question Discussion & Solution

The correct answer is Transpiration.

• Transpiration is the loss of water from a plant in the form of water vapour.

 Additional Information

• The amount of water that plants transpire varies greatly geographically and over time.
• The transpiration depends upon
  • Temperature,
  • Relative humidity,
  • Wind and air movement,
  • Soil moisture availability and
  • Type of plant.

Guttation

• Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of some vascular plants.

Evaporation

• Evaporation is the process by which water changes from a liquid to a gas or vapour.

Translocation

• The movement of sucrose and other substances like amino acids around a plant is called translocation.

The correct answer is 740 meters.

• The approximate height of Dhosi hill above sea level is 740 meters.

Key Points

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.

The correct answer is Ajmer.

Key Points

• The headquarter of the Rajasthan Revenue Council is located in Ajmer.
• Functions of Revenue Department:
  • All matters relating to levy and collection of Direct Taxes.
  • All matters relating to levy and collection of Indirect Taxes.

  • Ajmer is a city in the northern Indian state of Rajasthan.
  • It is situated on the lower slopes of the Taragarh Hill of that range. 
  • South of the city's artificial Ana Sagar Lake is Ajmer Sharif Dargah, the domed shrine of the Muslim Sufi saint Garib Nawaz. 

49 ÷ 7 = 7,

70 ÷ 7 = 10,

91 ÷ 7 = 13,

99 ÷ 7 = 14.14

So, 49, 70 and 91 are the multiples of 7 while 99 is not a multiple of 7.
