Answer 1

PLEASE GIVE ME A BRANLIAST ANSWER AND FOLLOW ME

1. Following are some of the key functions of antibody:
3. Binds to pathogens
4. Activates the immune system in case of bacterial pathogens
5. Directly attacks viral pathogens
6. Assists in phagocytosis
7. Antibody provides long-term protection against pathogens because it persists for years after the presence of the antigen.
8. It neutralizes the bacterial toxins and binds the antigen to enhance its efficiency.
9. They also act as the first line of defence for mucosal surfaces.
10. They ingest cells by phagocytosis.
11. Few antibodies bind the antigen present on the pathogens. These aggregates the pathogen and they remain in secretions. When the secretion is expelled out, the antigen is also expelled

Answer 2

Answer:

Hope it helps..........

Explanation:

Antibodies contribute to immunity in three ways / -

/ - Preventing pathogens from entering or damaging cells by binding to them (This process is cayvneutralization)

/ - Stimulating removal of pathogens by macrophages and other cells by coating the

pathogens. (Disease causing Micro-organisms)

/ - Triggering destruction of pathogens by stimulating other immune responses.
