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. If your actual fixed overhead cost is $4 per unit, you have an unfavorable variance of $1.
The major histocompatibility complex and its functions. The function of MHC molecules is to bind peptide fragments derived from pathogens and display them on the cell surface for recognition by the appropriate T cells.
From Proteopedia. Major Histocompatibility Complex (MHC) genes, and the proteins they specify, play centrally important roles in adaptive immune responses. Each MHC protein molecule contains a groove that is loaded with a peptide fragment derived from an intracellular protein.rom Proteopedia.
