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, a protein found in red blood cells, carries oxygen from your lungs through your bloodstream to all of your cells. Red blood cells are red because of hemoglobin.The amount of hemoglobin you need is based on age and gender. Men need between 14 and 18 gm/dL and women need 12 to 16 gm/dL. Your needs decrease with age. If your hemoglobin levels are too low, you may have anemia, which can leave your feeling fatigued or short of breath.
