Health

Scilla [17]3 years ago

Answer:

B cells produce antibodies, which bind to antigens and either block viruses and bacteria from entering cells (neutralizing antibodies) or trigger additional immune defenses. The two main types of T cells are CD4 and CD8 cells. CD4, or helper, T cells coordinate the immune response. These are the primary targets of HIV.

Answer:

Helper T-cells stimulate B-cells to make antibodies and help killer cells develop. Killer T-cells directly kill cells that have already been infected by a foreign invader. T-cells also use cytokines as messenger molecules to send chemical instructions to the rest of the immune system to ramp up its response.

Why does mcdonald's have so many calories?
Setler [38]
The fast food service Mcdonalds has many calories because all they sell there is just burgers, fries, sodas, and pies. Those foods are unhealthy and considered to be junk food with all that grease people like, the grease and fried food is what makes people fat since it got so many unhealthy calories. Some meals on their like the oatmeal and lettuce Mcwrap may be healthy but most of their food is unhealthy because the more calories it has, the more good it tastes so it brings in customers like a fisherman brings fish but instead of a scam, its just not giving your body what it really needs.
