What is the difference between a negative feedback system and a positive feedback system?
(a)- in a negative feedback system, the control center raises or lowers the set point until the signals from the sensor stop; in a positive feedback system, the set point remains constant.
(b)- in a negative feedback system, the organism is most likely experiencing a disease state. in a positive feedback system, the organism is most likely healthy.
(c)- in a negative feedback system, the consequences of the action can harm the animal; in a positive feedback system, the animal is not harmed.
(d)-in a negative feedback system, the control center signals the effector to go "on and off" to maintain a steady state (or stable equilibrium); in a positiv
