What is type of feedback in which a given action promotes more of the same?
The type of feedback that promotes more of the same action is positive feedback. It occurs when the result or outcome of an action increases the likelihood of that action being repeated or continued. Positive feedback reinforces and encourages the behavior or action that produced it.
What are some examples of a positive feedback loop and a negative feedback loop?
The most common by far is negative feedback, pretty much every hormone works through negative feedback. Take for example tiroxine: low levels of tiroxine induce production of TRH and TSH which in time increase production of tiroxine, and when the levels of tiroxine are high, it lowers the production of TRH and TSH, lowering production of tiroxine as well. Another example would be insulin: when blood sugar levels rise, the pancreas produces more insulin, and once it takes effect and blood sugar levels lower, the pancras stops the increased production. Positive feedback on the other hand is more rare, an example would be childbirthing, when the baby stretches the cervix, it induces production of oxytocin in the pituitary gland, which causes the contractions of the uterus, pushing the baby out and stretching the cervix even more, making the pituitary gland produce even more oxytocin
What is the difference between positive feedback control system negative feedback control system?
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).
When the body becomes dehydrated a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts This is an example of a?
feedback loop
Explain the difference between 'radiative forcing' and climate feedback'?
Radiative forcing is how potent a particular term, often a greenhouse gas, is in the atmosphere. It is like turning the sun up or down a little bit, since its units are W/m2 (just like that of solar radiation).Climate feedback refers to processes in the climate system that cause a feedback loop to occur. You might have warming temperatures that melt ice, and that will lower albedo which will cause the surface to heat up even more. That is a feedback (an example of a positive feedback).
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.
How does a neuron create a positive feedback loop?
through what can be seen as the domino effect. when depolarization opens sodium ion channel and that results to the opening of more sodium ion channels. this creates a positive feedback loop.
Does deforestation create a positive or negative feedback loop effect?
negative. I'm not sure what a feedback loop effect is but i know that the more you chop, the more air we lose, the more animals lose their homes, the less air our cows have to make my burgers!
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.

Is dehydration positive feedback?
It can an example of both a +ve or a -ve feedback loop. if +ve you get more and more thirsty until something happens (ie you go get a drink and thirst no more or you die)...
A blood clot stimulating the formation of more blood clotting is an example of?
Postive feedback
Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
What hormones are regulated by positive feedback under certain circumstances?
Oxytocin in the process of giving birth. Oxytocin causes uterine contraction, which causes the baby to push up against the cervix, which causes more oxytocin to be released. And the cycle continues until the baby is born.
What is a positive feedback loop increasing carbon dioxide?
The Oceanic Solubility Pump.Oceans absorb carbon dioxide (CO2) from the atmosphere.As the oceans get warmer, they absorb LESS CO2 than before.So MORE CO2 remains in the atmosphere.So the atmosphere gets warmer.This makes the oceans warmer.So they absorb less CO2. And so on.This is a positive feedback loop which increases the levels of carbon dioxide in the atmosphere.
What are the two types of feedback mechanisms?
There are two types of feedback mechanisms: positive feedback, which amplifies processes, and negative feedback, which stabilizes systems. For More Information : agilityportal.io
