Answer: ANTIBODIES
Explanation: Antibodies are also known as immunoglobulin Ig,it is a large blood protein that is produced in response to an Antigen inorder to counteract the effect of the antigen,when antibodies are produced,they combine chemically with some substances which the body recognizes as alien or foreign such as bacteria,viruses and foreign substances in the blood.
When some antibodies combine with antigens,they will activate a series of nine proteins known as complement that have been circulating in inactive form in the blood. This series of nine proteins will forms a partnership with antibodies,once they have reacted with antigen to help destroy foreign invaders and remove them from the body.
