Final answer:
The specific immune response is highly specific, meaning each antibody or B cell receptor is designed to recognize a specific antigen, demonstrating the efficiency and effectiveness of the immune system.
Step-by-step explanation:
The specific immune response is highly specific, which means that a given antibody or B cell receptor only recognizes a specific antigen. This specificity is possible due to the diversity of the variable regions that allow our immune system to target particular pathogens effectively and efficiently. The fact that the human body can produce more than 1012 different antibody molecules, despite having less than 50,000 genes, supports the idea of an immune system that is capable of a wide range of specific responses without needing a separate gene for each antibody.
