How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
How might the emergence of a positive feedback loop affect a system in homeostasis?
A positive feedback loop can disrupt a system in homeostasis by amplifying an initial change away from the set point, leading to an escalation of the deviation. This can push the system further out of balance and prevent it from returning to its original state. In extreme cases, a positive feedback loop can result in system failure or collapse.
Ozone layer depletion is an example of what kind of feedback loop?
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
A self-amplifying chain of physiological events is called?
Positive feedback loop. This is a process in which a change in a physiological parameter triggers responses that amplify the initial change, leading to a continuous increase in the parameter until a specific endpoint is reached.
What is a physiological feedback loop?
There are two kinds: one that turns off a reaction and one that adds to it. Negative feedback will stop a reaction when it is complete and will not allow it to continue to run. Most of our body systems work in this manner. It is some like filling a washing machine. It will turn off when full and begin to wash. The opposite is positive feedback, that washer will over flow. One of the best examples of positive feedback is the clotting mechanism.
How is a positive feedback stopped?

What is a vicious cycle?
positive feedback loop
What is sometimes called a''vicious cycle''?
positive feedback loop
What are four conditions in the cell that must be kept in the homeostatic balance?
- temperature - negative feedback loop - positive feedback loop - water balance
What happens during positive feedback loop?
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
What makes closed-loop op amp unstable?
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
Is the war on drugs a positive feedback loop?
Yes. Have fun proving it.

What are the component of oscillator?
It can contain active and passive components with a positive feedback loop.
Ozone layer depletion is an example of what kind of feedback loop?
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
Is the ADH feedback loop an example of positive or negative feedback?
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.
