Rhombus - Area. 1  As for all parallelograms, the area K of a rhombus is the product of its base and its height (h). 2  The area can also be expressed as the base squared times the sine of any angle... 3  or in terms of the height and a vertex angle... 4  or as half the product of the diagonals p, q...
Three broad categories of T cells. 1  Helper T cells augment the immune response by recognizing the presence of a foreign antigen and then stimulating antibody production and producing cytokines that âturn onâ or activate other T cells. 2  Regulatory T cells function in an opposite manner: they dampen or turn off the immune response.
The helper T would activate those B cells, and they would begin making antibodies. The antibody would circulate through the bloodstream, sticking to other chickenpox viruses and marking them for destruction. While the process takes time, eventually the immune system is capable of eradicating infection in this way.
