Hemoglobin is the oxygen-carrying protein inside red blood cells. It gives red blood cells their red color. People with anemia do not have enough hemoglobin. The body needs certain vitamins, minerals, and nutrients to make enough red blood cells. Iron, vitamin B12, and folic acid are three of the most important ones.
Which organelle would you expect to find in abundance in a muscle cell? Mitochondria because ATP is needed for muscle contraction and the mitochondria is the site of ATP production (powerhouse). Edit
Best Answer: Organelles. Example: nucleus, rough endoplasmic reticulum, ribosome, mitochondria, vacuole, chloroplast, etc. Organelles because it is a specialized subunit w/in a cell that carry out a specific function. An example would be the Golgi apparatus which helps to process and package the macromolecules such as proteins that are made by the cell. HOPE THIS HELPS! Yes, the answer is organelles. The other reply got it right on. All living things have cells containing organelles to carry out specific functions except bacteria and archaea.
