Final answer:
The blanks are correctly filled with hemoglobin, oxygen, iron, iron, and anemia. Iron is crucial for hemoglobin production and oxygen transport in the body, with anemia resulting from iron deficiency.
Step-by-step explanation:
In the body, iron is used to make hemoglobin, a component of red blood cells needed to carry oxygen to the body's tissues. Anemia (inadequate hemoglobin levels in the blood) can result from iron deficiency and negatively impacts children's ability to learn and adults' ability to work. In severe cases, it can result in anemia for pregnant women. The correct answer to fill in the blanks would be c) Hemoglobin; Oxygen; Iron; Iron; Anemia.
Iron is essential for hemoglobin synthesis and the transport of oxygen to the tissues. Anemia may manifest from a lack of red blood cell production, which can be due to insufficient iron levels in the body. Iron is stored in the body as protein compounds ferritin and hemosiderin, and it's essential for the process of cellular respiration and as a component of various enzymes and proteins such as myoglobin, cytochromes, and respiratory enzyme systems.
