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.
Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.Hemoglobin is made up of four protein molecules (globulin chains) that are connected together.The normal adult hemoglobin (Hbg) molecule contains two alpha-globulin chains and two beta-globulin chains.In fetuses and infants, beta chains are not common and the hemoglobin molecule is made up of two alpha chains and two gamma chains.emoglobin is made up of four protein molecules (globulin chains) that are connected together.
