Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support your explanation.

Answers

Yes, the importance of an element in the body related to its percentage of body weight.

That element that is present in a large amount are more important for the structure and function of the body. The human body is approximately 99% consist of six elements which is Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus.

The five elements are present in 0.85% on the basis of boy weight which is sulfur, potassium, sodium, chlorine, and magnesium so we can conclude that percentage of element in the body tells us about its importance.

Final answer:

The importance of an element in the body is not solely based on its percentage of body weight. Elements' importance is determined by their function and essentiality to biological processes. Oxygen, although abundant in the body, is necessary for cellular respiration and energy production.

Explanation:

The importance of an element in the body is not directly related to its percentage of body weight. While some elements may have a higher percentage in the body, their importance is determined by their function and essentiality to biological processes.

For example, oxygen is the most abundant element in the body and has a high percentage of body weight. This is because oxygen is essential for cellular respiration and energy production.

On the other hand, elements like iodine and iron may have a lower percentage in the body, but they are crucial for functions like thyroid hormone synthesis and oxygen transportation, respectively.

Answers

The difference of surface area to volume ratio of a large cell and a small cell is that the large cells have lower surface area volume ratio than the small cells.

Simply because the size of the cell is restricted by the surface area to volume ratio.
