Question Discussion & Solution

The correct answer is about 70% water.

Important Points

• The Top Four Elements Found in the Human Body: oxygen (65%), carbon (18.5%), hydrogen (9.5%), nitrogen (3.2%).
• The other trace elements (less than 0.01%) are boron (B), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), silicon (Si), tin (Sn), vanadium (V), and zinc (Zn).
• The six major nutrients are carbohydrates (CHO), lipids (fats), proteins, vitamins, minerals, water.
• The functions of water in the human body:
  • Water carries nutrients and oxygen to all cells in the body.
  • Water is required for breathing.
  • Water regulates your body temperature.
  • Water protects and cushions vital organs.
  • Water cushions joints.
  • Water removes waste.

Key Points

• Calcium (Ca) is the most abundant mineral in the body and is essential for a number of vital functions.
  • Also helps muscles relax and contract, important in nerve functioning, blood clotting, blood pressure regulation, immune system health.
• Iron (Fe), Part of a molecule (haemoglobin) found in red blood cells that carries oxygen in the body, needed for energy metabolism.
• Iodine found in thyroid hormone, which helps regulate growth, development, and metabolism.
• Chromium works closely with insulin to regulate blood sugar (glucose) levels.

Thus, ‘SEDATE’ can be coded as:

The pattern here is,

The Lungs is a part of the body’s Respiratory system.

Similarly, Heart is a part of the body’s Circulatory System.

The correct answer is Chittorgarh.

Key Points

• Bojunda Stromatolite Fossil Park is situated in Chittorgarh
• The Bojunda Stromatolite Fossil Park was in the news in May 2021 because the Department of Mines and Geology, in collaboration with the Chittorgarh district administration, proposed the creation of a 12-hectare geopark at this location.
• The original park was roughly 3.5 hectares in size, but it has now been reduced to 0.5 hectares.

Additional Information

• About Stromatolite
  • Stromatolites are layered bio-chemical mounds, column or sheet-like sedimentary rocks created in shallow water by biofilms of microorganisms capturing, binding, and cementing sedimentary grains.
  • Stromatolites are fascinating windows into the origins and evolution of life on our planet.​

The correct answer is Flash memory.

Key Points

• Flash memory is a type of memory that functions similarly to RAM and ROM.
• You can write data to flash memory just like you can to RAM, however, unlike ROM, the data isn't lost when the power is turned off. Read-only memory is referred to as ROM.
• Although the CPU can read from ROM, it cannot write to or modify it. ROM is a long-term storage medium.
• Random-access memory (RAM) refers to memory that the microprocessor can read from and write to. It's done in RAM when you construct something in memory.

Important Points

• The smallest and fastest memory in a computer is register memory.
• External memory, often known as secondary memory, refers to the numerous storage media that a computer might use to store data and applications.
• Cache memory, often known as cache, is a supplementary memory system that saves frequently used instructions and data in order for the central processing unit (CPU) of a computer to perform them more quickly.
