Question

what is the primary role of phosphorus in the human body? regulating blood pressure formation of bones and teeth, and being a part of nucleic acids providing energy for the body

Explanation:

To determine the primary role of phosphorus in the human body, we analyze each option:

• "Regulating blood pressure" is not a primary role of phosphorus. Minerals like potassium and sodium are more associated with blood pressure regulation.
• "Formation of bones and teeth, and being a part of nucleic acids" is correct. Phosphorus is a key component of bone and teeth (along with calcium) and is also a part of nucleic acids (DNA and RNA) as phosphate groups.
• "Providing energy for the body" is not a primary role of phosphorus. Carbohydrates, fats, and proteins are the main energy sources.

Answer:

B. formation of bones and teeth, and being a part of nucleic acids
