$18,750 unfavorable variable overhead spending variance = $360,000 â $341,250. Variance is unfavorable because the actual variable overhead costs are higher than the expected costs given actual hours of 97,500. $68,250 unfavorable variable overhead efficiency variance = $341,250 â $273,000.

The difference between Helper T cells and Cytotoxic cells is that the Helper T Cells have no cytotoxic or phagocytic activity. In other words, they cannot kill infected host cells (also known as somatic cells) or pathogens, and without other immune cells they would usually be considered useless against an infection.
T cells (Thymus cells) and B cells (bone cells). The function of T cells and B cells is to recognize specific non-self antigens, during a process known as antigen presenta â¦ tion.Once they have identified an invader, the cells generate specific responses that are tailored to maximally eliminate specific pathogens or pathogen infected cells.n response to pathogens some T cells, called T helper cells, produce cytokines that direct the immune response while other T cells, called cytotoxic T cells, produce toxic granules that contain powerful enzymes which induce the death of pathogen infected cells.
