Final answer:
The correct answer is that specific immunity does not respond the same to all attacks, which is a characteristic of the innate, not adaptive, immune system. Specific immunity improves after each exposure to the same pathogen.
Step-by-step explanation:
The trait that is NOT a characteristic of specific immunity is the one stating that the response is the same to all attacks. This trait refers to the innate immune response rather than the adaptive (specific) immune response.
Specific immunity, also known as adaptive immunity, is characterized by its ability to remember a pathogen after initial exposure. When the same pathogen is encountered again, the immune response is faster and stronger due to the memory cells developed during the first encounter. Unlike the innate immune system, the adaptive immune system is highly specific; it can distinguish different pathogens and target them with a tailored response.
The correct answer is D) Responds the same to all attacks, which is not a characteristic of specific immunity as specific immunity is tailored to each specific pathogen and improves upon subsequent exposures.
