The body uses atoms in different ways to accomplish different tasks. For example, one portion of the body's calcium supply strengthens bones, whereas another portion combines with proteins to stimulate blood clotting after tissue injury. Which of the following statements provides the most logical chemical explanation of calcium's ability to perform such different functions? a. The calcium in blood is a more reactive form of the atom and therefore has fewer protons than the calcium in bone.

b. there are many different isotopes of calcium, and the most reactive isotope is found in the bone.

c. the bone contains calcium salts, which are less reactive than the calcium ions found in the blood.

d. the calcium in blood has a lighter atomic mass than the calcium in bone and is in a more reactive form.

The correct option is;

c. the bone contains calcium salts, which are less reactive than the calcium ions found in the blood.

Explanation:

The most abundant metallic element found in the human body is calcium as it is present in the bones teeth and metabolism of the kidney

99 % of the calcium in the human body are found in the bones while the remaining 1 % circulates in the blood as ions

The bones of the vertebrate are made up of calcium salts such as calcium carbonate, calcium phosphate and calcium fluoride.
