Question

The distinction between the major and trace minerals reflects the:

a. ability of their ions to form salts
b. amounts of their contents in the body
c. importance of their functions in the body
d. capacity to retain their identity after absorption

Answer 1

The difference between major and trace minerals is based on the quantities of these minerals present in the body, with major minerals required in larger amounts than trace minerals.

Step-by-step explanation:

The distinction between major and trace minerals reflects the amounts of their contents in the body. Major minerals, which are needed in amounts larger than 100 milligrams per day, include sodium, potassium, chloride, calcium, phosphorus, magnesium, and sulfur. Trace minerals, required in much smaller quantities (≤150 mg/day), play vital roles as well but are needed in lesser amounts. For example, iron is vital for hemoglobin formation and zinc is important for immune function, but both are needed in smaller amounts than the major minerals.
