Question

The six major elements constitute body mass
(A) 85 %
(B) 92 %
(C) 98 %
(D) 99.4 %

Answer 1

Hint: The human body is made up of many compounds like oxygen, calcium, carbon, hydrogen, nitrogen, calcium and the phosphorus. They contribute to the human body functions in many ways. Out of these oxygen is the greatest constituent of the body mass.

Complete Answer:
- Practically 98 % of the human weight is major from the six major elements. The Oxygen offers 65 % of the human body weight. All living beings rely upon oxygen for endurance. Oxygen is essential for breathing; it makes 20 % of the air that we breathe in.
- Oxygen exists in our bodies primarily as water; it speaks to 89 % of the water weight. The carbon is 18 % in the human body weight. Carbon fastens are utilized to fabricate starches, fats, and proteins; breaking these chains gives the human body energy. Hydrogen 10 % of the human body weight.
- Hydrogen is a primary constituent of the DNA. Nitrogen is 3 % of the human body weight. Nitrogen is the most significant constituent of creature cells' cellular material, just as the amino acids that structure proteins, and the acids that structure the DNA.
- The calcium is 1.5 % of the human body weight. Calcium is a basic component in the human body, generally packed in teeth and bones. Phosphorus is 1 % of the human body weight. Potassium is 0.35 % of the human body weight.
- Red platelets contain the vast majority of the potassium found in the body. Sulphur 0.25 % of the human body weight. Sodium is 0.15 % of the human body weight.
Sodium capacities like potassium in sending nerve signals between the phones; it additionally adds to managing water sums in the body.

Thus, the option (C) is correct.

Note: Phosphorus is found in the human body as phosphates, a phosphorus ions related with four molecules of oxygen. The human skeleton and mind are stores of phosphates, where it is found as calcium phosphate. Phosphates are likewise present as the Adenosine triphosphate (ATP) energy particle, which discharges $7.3\,Kcalmo{l^{ - 1}}$ of energy to perform diverse organic capacities.
