when a woman's contractions speed up during labor is negative or positive feedback

In a positive feedback system, the output enhances or amplifies the input that started the process, causing a self-reinforcing loop. This means that an increase in the output leads to an increase in the input, continuing to drive the system further in the same direction.

A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment

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.

Negative feedback mechanisms work to maintain homeostasis by reversing a change in a physiological parameter, bringing it back to its set point. In contrast, positive feedback mechanisms amplify a change in a physiological parameter, leading to a continued deviation away from the set point until a specific endpoint or outcome is achieved.

Is the clotting of blood an example of positive or negative feedback?

Positive feedback

Feedback control is the process by which a system's output is monitored and used to adjust the system's input. This mechanism allows the body to regulate internal conditions within a narrow range, maintaining homeostasis. Negative feedback is a common type of control system where the system responds in a way that reduces the discrepancy between the desired and actual output.

positive feedback is always benificial but regenerative feedback may or may not.

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.

Positive feedback.

Negative feedback mechanisms work to maintain homeostasis by reversing a change in a system, while positive feedback mechanisms amplify and reinforce a change. An example of negative feedback is the regulation of body temperature – if body temperature rises, mechanisms kick in to lower it; whereas in positive feedback, childbirth contractions become stronger and more frequent to facilitate delivery.

A: Any feedback that contributes to the input is positive feedback

any feedback that subtract from the input is negative feedback

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.

An oscillator requires positive feedback to sustain oscillations by reinforcing the input signal and producing an output that is in-phase with the input. Positive feedback increases the overall gain of the system, allowing the circuit to overcome losses and maintain sustained oscillations without external stimuli.

What is the purpose of feelback how can you offer positive feedback

Yes because an amplifier with positive feedback is an oscillator.

In a feedback amplifier, positive feedback produces an output that is in-phase with the input signal. This can lead to instability and oscillation in the amplifier circuit. Positive feedback can increase the gain but at the risk of introducing noise and distortion.

Positive feedback enhances or amplifies a process or response, leading to an increase in the initial stimulus, while negative feedback regulates or dampens a process, maintaining stability or homeostasis within a system. Positive feedback moves a system away from its original state, while negative feedback moves a system back towards its original state.

Yes, both positive and negative feedback are components of homeostasis. Negative feedback helps to maintain a stable internal environment by reversing any deviations from a set point, while positive feedback amplifies the response to a stimulus, often to achieve a specific outcome in the body. Both types of feedback work together to regulate physiological processes and maintain balance within the body.

Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.

Feedback that is positive. Feedback that is positive. Answers and/or comments about something (that is being discussed or talked about) that are agreeable.

they are positive feedback and increase activity negative feedback.

Positive feedback is used in various contexts to reinforce desired behaviors or outcomes. However, in certain systems, unchecked positive feedback loops can lead to instability, unpredictability, or even system failure. In these cases, it can be dangerous as it intensifies the initial input without any regulatory mechanisms.

A: To feedback more of the same signal from the output to increase the input to farther increase the output and farther increase the input will ultimately saturate the system

A negative feedback system reverses changes in a controlled condition by detecting a deviation from a set point and activating mechanisms to counteract the change, bringing the condition back to the desired level. This helps maintain stability and homeostasis within the system.

some feedback r insulting or inappropriate. it depend on how u sort the question.

Question is on feed back system in control system. In a control system generally there is a setpoint to be achieved. Control system aims to achieve the setpoint. However due to inherent reasons, the actual keeps hovering around the setpoint. A good control system keeps the setpoint very close to the setpoint. Control system must know the actual value to make adjustment to achieve the setpoint. Actual value is fed back to the control system. This feed back is referred as negative or positive feedback. The feed back tells the control system that the actual value is lower or higher compared to set point. This is known as negative or positive feedback.

constructive feedback

Positive feedback loops are usually part of a larger system or process where the output intensifies the input, leading to an amplification of the initial signal. These loops can lead to rapid and exponential growth or change within the system. They are often important in biological systems, climate dynamics, and technological innovations.

it would be kind if you could leave a positive feedback

Or,

It would be kind of you to leave positive feedback.

Perhaps better:

I would be grateful if you leave your honest 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.

Negative feedback helps maintain stability in a system by counteracting any deviation from a set point, while positive feedback amplifies or enhances the deviation from the set point. Negative feedback loops help regulate processes in the body, such as temperature control, while positive feedback loops are less common and tend to lead to a change in the system.

positive feedback mechanism.

Positive feedback in economic systems can cause boom-then-bust cycles. A familiar example of positive feedback is the loud squealing or howling sound.

Thank you for writing. I appreciate your feedback and your perspective.

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.

Positive feedback tends to magnify a process or increase its output by reinforcing and amplifying the desired behavior or outcome. This can lead to exponential growth or improvement in the system or process.

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.

It depends on wether it's a negative or a positive feedback system.

A Wien bridge oscillator produces sine waves. In order for the sine waves to maintain a steady amplitude, a positive feedback system is used with some sort of control to limit gain. In order for the positive feedback system to work, the waves being "fed back" to the amplifier have to be in phase with the waves being generated. Thus, you need a phase shift network to ensure that the phases of the waves match, which in the case of a positive feedback system means that the generated waves need to go through a 360o phase shift during the feedback process.

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.
