Do not switch on the power supply until2.Switch on and leave for about 5 min. Watch what happens and record your results.3.E Making . Iron Oxide. (Rust). Rust. Rust is scientifically called oxidation, which occurs when oxygen comes in long-term contact with certain metals. Over time, the oxygen combines with the metal at an atomic level, forming a new compound called an oxide and weakening the bonds of the metal itself. If the base metal is iron or steel, the resulting rust is properly called iron oxide. . Lecture . 7 . 1. White blood cells. Platelets. Red blood cells. Artery. Introduction . . 2.

Anemia.  occurs when you have a decreased level of . hemoglobin. in your red blood cells (RBCs). . Iron is an essential nutrient that, is required for the production of healthy red blood cells (RBCs). It is a critical part of hemoglobin, the protein in RBCs that binds oxygen in the lungs and releases it as blood circulates to other parts of the body. A serum iron test measures how much iron is in your serum. The serum iron test can reveal abnormally low or high blood iron levels. .
