Answer:
Iron is a major component of hemoglobin, a type of protein in red blood cells that carries oxygen from your lungs to all parts of the body. Without enough iron, there aren't enough red blood cells to transport oxygen, which leads to fatigue.
Explanation:
Answer: The presence of iron in hemoglobin is important to investigators because it can provide useful information for medical diagnosis and forensic investigations.In medical diagnosis, the iron in hemoglobin helps healthcare providers assess a patient's blood oxygen levels and screen for conditions such as anemia, sickle cell disease, and thalassemia. Iron-deficiency anemia, for example, is a common condition caused by insufficient iron in the body, which affects the production of hemoglobin and can lead to low oxygen levels and fatigue.In forensic investigations, hemoglobin can be used as a tool to determine the presence of blood at a crime scene. The iron in hemoglobin makes it possible to detect blood even in small amounts using a chemical test called the Kastle-Meyer test. This test involves adding a solution of phenolphthalein and hydrogen peroxide to a sample, which reacts with the iron in hemoglobin to produce a pink color. This can help investigators locate and analyze evidence, such as blood stains or spatters, to help solve crimes.
