Negative feedback is a reaction that causes a decrease in function. Using a thermostat, it senses the temperature of an area and responds by either turning on or off the heater or air conditioner.

∙ 11y agoA thermostat generally operates as a simple negative feedback controller. It uses the actual temperature to "feedback" to compare to the desired temperature or set point and tries to reduce the error between them. In the case of simple air conditioning only, the error or the difference between the desired temperature and actual temperature does not really matter. There either is error or not. If the error is positive (input minus feedback) the air conditioning turns on. If the error <= 0 nothing happens unless you switch over to heat.

When body temperature rises a center in the brain initiates physiological changes to decrease the body temperature is an example of negative feedback or positive feedback?
This is a very good example of negative feedback.
Is the ADH feedback loop an example of positive or negative feedback explain?
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.
Why is temperature control is regarded as an example of a negative feedback?
Temperature control is regarded as an example of negative feedback because it is used in homeostasis.
Why is the type of feedback that maintains homeostasis referred to as negative feedback?
Once the desired effect has taken place, feedback is sent to stop any further action by the system. This is called negative feedback because it stops (or lessens) the output. An example of negative feedback: Low body temperature -> shivering -> temperature rises -> stop shivering There are some forms of positive feedback, where the production of something actually leads to further production.
The increasingly forceful labor contractions during childbirth are an example of?
Positive feedback
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
Is the thirst sensation when you get dehydrated an example of a negative or a positive feedback?
negative

What is an example of a negative feedback in human body?

What are the example of negative and positive feedback in geography?
A negative feedback would be if the planet heats up, the glaciers will melt, lowering the albedo effect of the snow, and in turn causing the planet to heat up more That is positive feedback, not negative. Positive feedback enhances the initial stimulus, negative feedback reverses the initial stimulus. The planet starts by heating up, then heats up even more, which is positive feedback.
What is a feed Back?
It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.
What is a biological feed back?
It depends on whether it is positive or negative feedback. Most biological organisms exhibit both negative and positive feedback, including humans. An example of positive feedback is contractions during childbirth. Negative feedback is blood sugar regulation based upon the release of insulin into the bloodstream at necessary times.
How does positive feedback maintain cellular homeostasis?
Perhaps you don't understand the meaning of positive and negative feedback. Positive feedback keeps adding to a process. Negative feedback doesn't. If a person fills a bathtub, positive feedback will continue the filling even if it runs over. Negative feedback will turn the water off when the tub is filled. So, negative feedback maintains homeostasis. Homeostasis means "steady state". When a processes is completed, it turns it off. Example: Blood sugar levels remain in a certain range.
Types of feed back?
In sociology, the two main types of feedback are positive and negative. An example of positive feedback would be receiving an A+ on a paper one has studied hard for. Negative feedback would be to receive a poor grade in a test the person hasn't studied for.
Why negative feedback amplifier is preferred to positive feedback amplifier?
The negative feedback tends to stabilize the circuit; positive feedback would make it more unstable. For example, the "beta" of a transistor OF THE SAME SERIES - this is basically the amplification factor - may vary between 100 and 1000. With negative feedback, the circuit is hardly affected by these changes in beta - at the cost of a reduced amplification.
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.
