If you mean positive feedback in the biological sense of the body's response to change, a fever is positive feedback because it's very presence causes it's increase.
Positive feedback is when a change in the environment of your body triggers a reaction which increases the change. It is often dangerous but somtimes useful eg during childbirth.
When you have a fever, your body also thinks you have hypothermia (extremely cold) so it attempts to warm you up. (which It does this by constricting surface capillaires cuts of blood supply to areas in which it would cool), shivering and an increased muscle tone. These changes cause the body to heat up more, thus increasing the severity of the fever itself.
Hope that makes sense :) I learnt that today believe it or not XD
Is the clotting of blood an example of positive or negative feedback?
oxygen loading is a positive feedback response
positive feedback is always benificial but regenerative feedback may or may not.
Positive feedback.
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
Positive feedback Positive feedback
The positive feedback loop is terminated by the end of childbirth...
A: POSITIVE feedback will force the amplifier to sit at its rail saturated
No it is positive feedback
Postive feedback
A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment
