Answer:
The answer is d. 3,4,2,1,5
Explanation:
The correct sequence is:
- Antigens from a pathogen bind to antigen receptors on Lymphocytes.
- Lymphocyte specific to antigens from a pathogen become numerous.
- Lymphocytes secrete antibodies
- Pathogen is destroyed.
- Only memory cells remain.
Adaptive Immune System/Acquired Immunity:
Adaptive immune system involves the part of immune system that is contains specific and highly specialized cells to target specific pathogens. Acquired immunity involves antigen specific antibodies that bind and mark a specific pathogen. This pathogen is then cytotoxically destroyed by specific effector cells of the immune system. Acquired immunity is also characterized by the production of memory cells at the time of mass production of antigen specific antibodies. These memory cells remain long after the pathogen has been destroyed to protect against consequent attacks from the same pathogen.
