To calculate the variance, subtract your actual fixed overhead cost from your standard overhead cost. If the actual cost is higher than the fixed cost, the cost variance is unfavorable. For example, your standard fixed overhead cost is $3 per unit.
The major role of hemoglobin is to carry oxygen from the lungs to the tissues and return carbon dioxide (CO2) from the tissue to the lungs.
The main function of red blood cells is the transport of oxygen from the lungs to the body's cells. Red blood cells contain a protein called hemoglobin that actually carries that oxygen.n each molecule of hemoglobin there are four iron atoms. Each iron atom binds with one molecule of oxygen. The iron in hemoglobin is what gives blood its red color. Thirty-three percent of a red blood cell is hemoglobin. The normal concentration of hemoglobin is 15.5 grams per deciliter of blood in men.
