Question

select the correct answer from each drop - down menu. minerals are micronutrients required by the body for various key functions. the mineral is required to carry oxygen in the blood to all body tissues, and is a rich source of this mineral. options for the first drop - down: calcium, iron, sodium

Explanation:

To determine the mineral required to carry oxygen in the blood, we recall that iron is a key component of hemoglobin, which is responsible for transporting oxygen. Calcium is important for bone health and muscle function, and sodium is involved in fluid balance and nerve function. So the mineral needed for oxygen transport is iron. For a rich source, foods like red meat, spinach, etc., are rich in iron, but from the context of the drop - down (even though the second drop - down options aren't fully shown, based on the first part), the first drop - down answer is iron.

Answer:

First drop - down: iron
