Question

identify the immune response described as nonspecific or specific. uses memory cells to fight off an infection from a pathogen evident by a sneeze, cough, fever, or other physical symptom recognizes antigens present on pathogens and attacks the pathogen with antibodies builds immunity to specific diseases that had previously entered the body does not target specific pathogens

Explanation:

1. "uses memory cells to fight off an infection from a pathogen"

Specific immune response (adaptive immunity) involves memory cells that "remember" previous pathogens to mount a faster response. Nonspecific is innate, no memory cells. So this matches specific response.

Nonspecific (innate) responses like sneezing (to expel pathogens), fever (to inhibit pathogen growth) are general, not targeting specific pathogens. Specific responses are more targeted (antibodies, memory cells) and less about these general symptoms.

Specific immune response (e.g., humoral immunity) uses antibodies that recognize specific antigens on pathogens. Nonspecific doesn't use antibodies against specific antigens. So this is specific response.

Answer:

specific response

2. "evident by a sneeze, cough, fever, or other physical symptom"
