Question Discussion & Solution

The correct answer is 68 Assembly Constituencies.

• As of June 2020, the state of Himachal Pradesh has been divided into 68 Assembly Constituencies.

Key Points

• Himachal Pradesh:
  • In 1970, the Union Territory of Himachal Pradesh was elevated to the status of the state.
  • Its summer capital is Shimla.
  • Its winter capital is Dharamshala.
  • It has a total of 4 Lok Sabha seats and 3 Rajya Sabha seats.
  • Current Governor: Bandaru Dattatreya
  • Current Chief Minister: Jai Ram Thakur

The pattern followed here is:

Hence, 119 is the next term in the series.

The correct answer is Bone-marrow.

Key Points

Red blood cell:

• Red blood cells (RBCs) are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues via blood flow through the circulatory system.
• RBC is formed in Bone Marrow.
• RBCs take up oxygen in the lungs, or in fish the gills, and release it into tissues while squeezing through the body's capillaries.
• The cytoplasm of erythrocytes is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood.
• Each human red blood cell contains approximately 270 million of these hemoglobin molecules.
• The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiological cell function such as deformability and stability while traversing the circulatory system and specifically the capillary network.

Additional Information

• Red blood cells are thus much more common than the other blood particles: there are about 4,000–11,000 white blood cells and about 150,000 - 400,000 platelets per microliter.
• Human red blood cells take on average 60 seconds to complete one cycle of circulation.
• The blood's red color is due to the spectral properties of the hemic iron ions in hemoglobin.
• Each hemoglobin molecule carries four heme groups; hemoglobin constitutes about a third of the total cell volume.
• The normal pH range of blood is between 7.35 to 7.45. This means that blood is naturally slightly alkaline or basic.

The correct answer is from gypsum.

Key Points

• Plaster of Paris is manufactured by heating gypsum at 423K or 150°C/300° F.
• On heating gypsum at 423 K, it loses water molecules and becomes calcium sulfate hemihydrate.
• This product is known as the plaster of Paris.

Additional Information 

• Characteristics of Gypsum Plaster:
  • Plaster of Paris is usually a white dry plaster powder.
  • It can be effectively worked with metal apparatuses or even abrasive sheets and can be shaped as per the requirements.
  • The strength of plaster of Paris is not as strong as other compounds and it often requires external support when a large amount is used.
  • It is often applied in the form of a quick-setting paste with water. 

The correct answer is Vitamin A.

Key Points 

• Night blindness is the inability to see well at night or in poor lighting conditions. 
• Night blindness is also called nyctalopia.
• Night blindness is often caused by Vitamin A deficiency.
• Night blindness is also caused by nearsightedness or cataracts.
• Foods that provide Vitamin A are carrots, sweet potatoes, eggs, milk, milk products, etc.
