Which one of the following statement is correct for negative feedback? Select one: a. In some cases, negative feedback systems carry the mechanism for their own destruction without being fatal to the organism, but to a part of the organism. b. Negative feedback can move the control parameter to a value outside that normally maintained by positive feedback. c. In a negative feedback a molecular reaction can have such a large drop in free energy that the reaction is essentially irreversible. d. A negative feedback system is stable over time, maintaining a steady state.
