20 do viruses have metabolisms? ? one requirement of living things is that they reproduce. do viruses meet this requirement? are viruses made of cells?

Viruses do not have metabolisms they spread to other cells, which spread the virus. In a way, viruses can reproduce, when the virus spreads t cells, like I mentioned above. Viruses are not living things, although they ae composed of carbohydrates, lipids(fats), proteins, and nucleic acids. They can only enter cells in order to actually do something. I hope this helps!

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
