The mineral is required to carry oxygen in the blood to all body tissues, and is a rich source of this mineral.
first blank is either calcium, iron or sodium
second blank is vegetable oil, red meat or milk

Answer 1

The answer would be: iron; red meat

Iron is needed to form heme part of hemoglobin. Hemoglobin is the molecule from red blood cells that could carry oxygen and carbon dioxide. Food that rich in iron should be red meat or liver. Only a few vegetables have high iron like spinach. A person with low red meat diet (like in vegetarian) will have high risk of iron deficiency.
