Final answer:
Decreased hemoglobin levels are seen in Iron-deficiency anemia.
Step-by-step explanation:
Anemia is a disease that occurs when there is not enough hemoglobin in the blood to carry oxygen to body cells. Hemoglobin is the blood protein that normally carries oxygen from the lungs to the tissues. Anemia leads to a lack of oxygen in organs.
Iron-deficiency anemia is the most common type of anemia. It occurs when the body does not receive enough iron. Since there is not enough iron, hemoglobin, which needs iron to bind oxygen, cannot function properly. Therefore, decreased hemoglobin levels are seen in iron-deficiency anemia.
Therefore, decreased hemoglobin levels are seen in Iron-deficiency anemia.
