Which of the following is NOT an example of negative feedback as a tool in homeostasis? A) When oxygen levels are low, a hormone is released to stimulate the production of red blood cells. B)When blood sugar rises, signals are sent to the liver to increase bile production. C) When the body is hungry, metabolism slows down to conserve energy. D)When blood pressure increases, signals are sent for the heart rate to slow down.
Blood clotting is a positive feedback.Explanation:
All the physiological process occurring in the body are monitored by two types of mechanism called negative feedback and positive feedback.
Positive feedback is the reaction which occurs with the feedback from the actions the system has performed. The blood clot occurs with palette formation which is regulated with the blood lose (continuous feedback).
Negative feedback is a reaction that is the invert of the change distinguished, meaning it capacities to decrease the change. A change is recognized by a receptor and an effector is made to incite a contrary impact which facilitates further reaction.
The physiological process such as shivering, sweating and digestion are examples of negative feedback.
