Question

the text emphasizes that each antibody binds to just one kind of antigen. 1 point what is the primary advantage of this high specificity? it ensures that the immune response is precisely targeted to the specific invading pathogen, avoiding damage to the bodys own cells. it makes antibodies cheaper for the body to produce, as they have a very simple structure. it allows a single antibody to fight many different types of pathogens simultaneously. it allows the antibody to destroy the pathogen without needing help from other cells like phagocytes. t cell activation requires another leukocyte (like a b cell) to first engulf a 1 point pathogen and present its antigen. what is the most logical reason for this multi - step activation process? it ensures that t cells only activate in response to a confirmed foreign threat, preventing accidental attacks on healthy body cells. it is the only way a t cell can absorb the nutrients it needs to divide into an army. it slows down the immune response to give the pathogen time to replicate. it allows the t cell to choose which type of cell it will become (helper, cytotoxic, or regulatory)

Explanation:

Antibodies' high - specificity ensures the immune response targets only the invading pathogen, protecting the body's own cells. For T - cell activation, the multi - step process confirms a foreign threat before activation, preventing auto - immune attacks.

Answer:

1. It ensures that the immune response is precisely targeted to the specific invading pathogen, avoiding damage to the body's own cells.
2. It ensures that T cells only activate in response to a confirmed foreign threat, preventing accidental attacks on healthy body cells.
