because a change in one factor (the temperature) causes a response that brings that factor back to normal.

The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.

positive feedback loop because cause increases the effect. thank you very much!
Feedback oscillators have a closed loop gain of

dik Not sure what they mean by that but... A good example of a positive feedback loop is the increased production of insulin by our pancreas. After a meal we may have heightened blood sugar levels. The endocrine system triggers insulin production in the pancreas to counteract this rise and return our blood sugar levels back to normal. Once normality has been reached the endocrine system signals our pancreas to cease the production and release of insulin. Actually, that is an example of a negative feedback loop. Negative feedback loops negate an action, while positive feedback loops encourage it. An example of a Positive feedback loop is childbirth, the body increases the amount of oxytocin in the blood to encourage contractions in order to birth the baby.
You must give "which of the following" for us to answer your question.
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
Feedback Loop - 2008 is rated/received certificates of: UK:PG
A: DEFINITELY NOT Open loop is defined as no feedback. any kind of negative feedback will reduce the gain
