the ability of our immune system to attack abnormal or foreign cells but spare our own normal cells is called:
innate immunity.
nonspecific immunity.
self-tolerance.
adaptive immunity.
question 13
1 pts
because t cells attack pathogens more directly, t - cell immune mechanisms are classified as______immunity.
antibody - mediated
cell - mediated
nonspecific
none of the above are correct.

Explanation:

• Question 12:
• Innate immunity is the body's first - line, non - specific defense.
• Nonspecific immunity is a general term for defenses that do not target specific pathogens.
• Adaptive immunity is more specific and involves the immune system "remembering" pathogens.
• Self - tolerance is the immune system's ability to recognize self - cells as non - foreign and not attack them.
• Question 13:
• Antibody - mediated immunity involves B - cells and antibodies.
• Cell - mediated immunity involves T - cells directly attacking pathogens.
• Nonspecific immunity is general and not related to T - cell direct attack in this context.

Answer:

• Question 12: self - tolerance.
• Question 13: cell - mediated.
