Is breathing an example of positive feedback?
no; breathing in is an example of negative pressure caused by the contraction of the diaphragm. followed by breathing out, which is cause by movement of air from high pressure to low when the diaphragm relaxes
Oxygen loading a positive of negative feedback process?
Oxygen loading is a positive feedback process where increased oxygen levels in the blood stimulate further loading of oxygen onto hemoglobin molecules. This results in more efficient oxygen transport to tissues. Negative feedback processes, on the other hand, involve a response to reduce or counteract a stimulus, aiming to maintain homeostasis.
How does negative feedback mechanism and positive feedback differ?
A negative feedback will stabilize an amplifiers positive feed back will force the amplifier to either saturated state. this will hold true for a system too. A more general answer follows. 1. Feedback: Getting information about what just happened and responding to it. 2. Negative Feedback: The response lessens the output. 3. Positive Feedback: The response increases the output.
How are negative and positive feedback involved in homeostatic regulation?
Negative feedback occurs when the output of a system reacts to cancel out the effects of an input of a system, as opposed to positive feedback (in which the actions/output is intensified or increased). The more negative, the more stable. Thus, with things being canceled out, the body maintains homeostasis. An example of negative feedback in action is the maintenance of blood glucose levels and body temperature. With input of sugar, insulin is released to stabilize the body (on the other hand, without insulin, diabetes can be diagnosed). With a raise in body temperature, blood vessels and pores are opened to release heat.
What effect does negative feedback have on homeostasis?
Imagine this process in the body: The brain tells your stomach to release chemical A. Chemical A causes Chemical B to be released. Chemical B has an effect on your body. Chemical B also tells the brain to stop releasing Chemical A. The negative feedback is Chemical B telling the brain to stop. If the brain keeps releasing chemical A, then chemical B will keep being released and do things to your body and it would never stop. This creates an imbalance. Therefore, the end products of any reaction in the body tell the source to
How does negative feedback work?
To remove the distortion ... ANSWER: It does not reduce distortion but rather make the circuit stable. There can be distortion even with negative feedback by bad design in other word feedback does not reduce distortion.
What is the difference between positive feedback and negative feedback?
Positive feedback speeds up reactions while negative feedback slows them down. Positive feedback goes with the force that put the body out of homeostasis in order to get it over faster. For example, during childbirth, the body goes with it in order to get it over faster so that the body can return to homeostasis. On the other hand, negative feedback opposes the action. For example if your body temperature drops, your receptors in your body send a message to your brain to tell it your cold. Your brain then sends a message to your muscles to shiver to help warm you up.
How is the menstrual cycle an example of the body's use of negative feedback?
The menstrual cycle is regulated by negative feedback involving hormones such as estrogen and progesterone. When hormone levels drop, it triggers the release of other hormones to stimulate the uterine lining shedding (menstruation). Once hormone levels rise again, it signals the end of menstruation and the start of a new cycle, maintaining balance through negative feedback mechanisms.
What is output feedback design?
A: A system ideally should have infinite gain but if that is so then it will saturate to one state or the other Feedback [negative] insure that will not happen the feedback will control the saturation making it stable.
What is the difference between positive and negative feedback cycles?
Most of our bodies systems run on negative feedback. This means, for example, say you are hungry. Your body produces and releases a signal and when you are fed, your body realizes it needs to stop making you feel hungry. So other hormones/signals are released to quiet down the initial one. Very few of ourbodies systems run on positive feedback. One example is labor contractions. A signal is given in the body to have a small contraction, that contraction happens and instead of the body saying "okay mission accomplished" and quiteig down the first signal (like in negative feedback) it actually INCREASES the amount of the initial signal so you get more and more powerful contractions. Hope I explained that so you understand it!
Is breathing an example of positive feedback?
no; breathing in is an example of negative pressure caused by the contraction of the diaphragm. followed by breathing out, which is cause by movement of air from high pressure to low when the diaphragm relaxes
Does the enzyme that undergo negative feedback have any other function than to be regulated by its product?
Yes, enzymes that undergo negative feedback regulation typically have other important functions in the cell or organism. These enzymes are often involved in key metabolic pathways and play critical roles in maintaining cellular homeostasis and carrying out essential biological processes. The negative feedback regulation helps control the rate of these enzymatic reactions to ensure optimal function.
Why is feedback useful?
So u can understand the subject/person better
Has Spearmint Rhino received a lot of negative feedback?
"Yes, feminist groups are constantly giving spearmint rhino and many other gentleman's clubs negative feedback. Most of the reviews posted online by people who frequent the place seem to be complimentary."
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 ).
Why do you feedback?
A: Follow this the amplifier has infinite gain. So any input will slew it to either power supply buss as saturated. Now take this saturated signal and feed it back to the input since the feedback is negative in nature to the input it will force the output to reverts to the other buss voltage. But the since negative feedback is a proportion of the output signal it will reach a point where it is stabilized and linear. That is the intention of negative feedback feed back some output signal to stabilize to a happy stability or linear with reduced feedback of course

Oxygen loading is a positive feedback process where increased oxygen levels in the blood stimulate further loading of oxygen onto hemoglobin molecules.
