Question

Bobbi’s body has just detected a virus. Which part of the negative feedback loop will work to fight that virus? (1 point) Responses stimulus stimulus sensor sensor effector effector control

Answer 1

In a negative feedback loop, the part that works to fight a virus after it has been detected is the **effector**. Effectors are responsible for carrying out responses that counteract the initial stimulus—in this case, the presence of the virus. They may include immune cells or other mechanisms that work to eliminate the virus from the body.
