Answer
Phagocytes are a type of white blood cell that play a critical role in the innate immune response. They can engulf and digest pathogens and debris, demonstrating a non-specific response because this action does not target a specific pathogen but rather any non-self material.
Step 2
B. cytotoxic T cells releasing chemicals into infected cells

Answer
This action is part of the adaptive immune response rather than a non-specific response. Cytotoxic T cells specifically target and eliminate infected cells based on the recognition of specific antigens.

Answer
The production of memory T cells is a hallmark of the adaptive immune system. These cells are tailored to recognize specific pathogens the body has encountered before, thus it is not a non-specific response.

Answer
This process is also part of the adaptive immune response where B cells are activated and cloned in response to specific antigens, leading to the production of antibodies. Therefore, this is not a non-specific response.
