Hi there!
The answer is
Sun, Earth, capital building, human, atom
Since everything has its own gravity and the amount of gravity depends on the mass of an object, we can assume that since the sun is heavier than the earth which is heavier than a capital building which is heavier than a human which is heavier than an atom, the amount of gravity also goes in this order.
Hope this helps!
Answer:
Adaptive immune defense system consists of lymphocytes like B-lymphocytes and T- lymphocytes. B-lymphocytes provides humoral immunity while T- lymphocytes provide cell-mediated immunity to the body.
99% of lymphocytes circulate freely in the blood and lymph. B lymphocytes differentiate into plasma B cells and B memory cells when interact with antigen presented by T helper cells.
Then plasma cells secrete antibodies in the circulation which binds to extracellular antigens through antigen-binding site. Then the bounded antigen is recognized by receptors present on phagocytic cells. This receptor binds the Fc region of antigen bounded antibody and destroy the antigen by phagocytosis.
