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.
Dehydration is not an example of positive feedback. Positive feedback loops amplify or reinforce a pathway or process, while dehydration is a state where the body lacks adequate water, leading to negative effects on various bodily functions.
positive feedback of estradiol that increases the release of LH
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.
This is known as a feedback loop. When a system's output influences its input in a way that reduces the output, it can lead to the system shutting down or destabilizing. This feedback loop can have either positive (amplifying) or negative (stabilizing) effects on the system.
A neuron creates a positive feedback loop by amplifying and reinforcing the initial signal it receives. When a neuron receives an excitatory signal, it triggers an action potential that leads to the release of neurotransmitters, which further activate neighboring neurons, leading to a continuous cycle of activation and signaling. This amplification process results in a self-reinforcing loop that can enhance the strength and duration of the signal being transmitted.
The positive feedback loop is terminated by the end of childbirth...

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.
Yes. Have fun proving it.
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.
It can contain active and passive components with a positive 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.
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. 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.
