. What happens to the bunny population if a friend is never added? What happens when you add a friend?

 If a friend is never added then the bunny will die, but when you add a friend the bunnies sexually reproduce, and the population grows.

Hope this helps Stay safe and have a Merry Christmas :D

I just want to say that my account got deleted yesterday and i would love if i got at least 18-25 friends by Christmas :D

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.

that is wrong, its not thymus.
