Question

Organisms that don't recognize their own cells.

Answer 1

Answer: C. Autoimmune

An “autoimmune response” is when the body senses danger from an oncoming virus and starts to attack it. Sometimes, healthy cells of the body are caught in the midst of this attack, and are not “recognized” as separate from the virus. Choice C is then closest to the correct answer.

Also, this belongs in one of the science categories. :)
