Question Discussion & Solution

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.

All given numbers are cube except 400. 400 is a square of 20.

The pattern repeat alternatively.

The correct answer is A Central processing unit.

Key Points

• Central Processing Unit(CPU)
  • A CPU is also called a central processor, main processor, or just processor, is the electronic circuitry that executing instructions comprising a computer program.
  • The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.
  • The fundamental operation of most CPU's regardless of the physical form they take is to execute a sequence of stored instructions called a program. 
• Instructions cycle in CPU
  • All CPU's follows the following steps in order to complete their operations:
    1. Fetch: The first step, involves retrieving instructions from the program memory.
    2. Decode: The instruction that the CPU fetches from the memory determines what the CPU will do, which is decoded by the instructor decoder.
    3. Execute: In this step, all the desired functions are performed as per the instructions decoded.
• Intel Core
  • ​Intel core are streamlined computers CPU marketed by Intel Corporation.
  • Brand Names: Core, Core 2, Core i3, Core i5, Core i7, Core i9
  • Launched: January 2006
  • Founders: Gordon Moore Robert Noyce
  • Headquarters: Santa Clara, California, USA

Additional Information

The correct answer is 1921.

• The Begun Kisan Andolan was started in 1921.

Key Points

• Begun Kisan Andolan:
  • It was one of the farmer's movements of Rajasthan during British Raj in India.
  • It was started in Menal village in 1921.
  • Begun is a village in Chittorgarh district.
  • Vijay Singh Pathik was the leader of this movement to Ramnarayan Chaudhary.
  • In 2023, an agreement was made between Rajasthan Sewa Sangh and Rawat Sawai Anup Singh Ji to settle the dispute but it was opposed by the government naming it a Bolshevik agreement and the government appointed a government employee in the place of Thikanedar under its Munsarmat policy. 
  • The leadership of this movement was later handed over to Vijay Singh Pathik.
