What are effectors?

• Receptors that detect changes in the body

• Structures that process sensory information in the body

• Structures that allow for appropriate responses to detected changes

• Molecules that reduce the likelihood of survival

• Tissues that reduce the likelihood of reproduction

What are the two main effectors in the body?

What occurs in negative feedback? Select 2

• Conditions are returned to an ideal point

• Conditions are distanced from an original point

• A change is reversed

• A change is embraced

• Survival and/or reproduction is disrupted

What is a key feature of negative feedback?

• Once the change is reversed, the mechanism is shut down

• The change is embraced in an amplified manner with conditions changing rapidly

• Once the change is reversed, the mechanism continues

• The change is embraced in an amplified manner with conditions changing slowly
