with Solved Questions | Graded A+
Question 1.
Receptor .
Answer: body structure that monitors changes in a controlled condition and
sends input to a control center
Question 2.
Stimulus .
Answer: a signal to which an organism responds
Question 3.
control center .
Answer: processes the signal and sends instructions
Question 4.
Effector .
Answer: an organ or cell that acts in response to a stimulus.

negative feedback .
Answer: A primary mechanism of homeostasis, whereby a change in a
physiological variable that is being monitored triggers a response that
counteracts the initial fluctuation.
