$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 regulatory T cells (Tregs pronunciation: /ËtiËrÉÉ¡/), formerly known as suppressor T cells, are a subpopulation of T cells which modulate the immune system, maintain tolerance to self-antigens, and prevent autoimmune disease.

They are effective at killing foreign invaders and can release substances that enter a virus and destroy it before it has the opportunity to replicate..
