Question

Important electrolyte(s) in the body include ________.

1) K+
2) Na⁺
3) Ca2+
4) Cl-
5) HC03-
6) H+
7) Mg₂⁺
8) all of the above
9) only a through f

Answer 1

The correct answer is option 8) 'all of the above,' as important electrolytes in the body include sodium, potassium, calcium, magnesium, chloride, bicarbonate, hydrogen ions, and other minerals like phosphate.

Step-by-step explanation:

The important electrolytes in the body include sodium ion (Na+), potassium ion (K+), calcium ion (Ca2+), magnesium ion (Mg2+), and chloride ion (Cl-). Each of these ions has specific roles in the body, such as regulating body fluids, cell functions, muscle contraction, nerve control, and enzyme activity. Ions like bicarbonate (HCO3-) and hydrogen ion (H+) also play critical roles in maintaining pH balance and other bodily functions.

Therefore, the correct answer to which important electrolyte(s) are included in the body is option 8), "all of the above", which encompasses sodium, potassium, calcium, magnesium, chloride, bicarbonate, hydrogen ions, and includes other minerals mentioned such as phosphate that are also important electrolytes in the body.
