A positive feedback system is driven by the amplification of a process, where the output enhances or increases the input, leading to a greater response. This typically occurs when a change triggers mechanisms that further accelerate that change, such as in the case of blood clotting or childbirth, where the release of certain hormones intensifies the process. Unlike negative feedback, which seeks to stabilize a system, positive feedback can lead to exponential growth or rapid change until a specific endpoint is reached.

If a response enhances the original stimulus the system is a?
positive feedback system
Which feedback mechanism causes the variable to deviate further and further from its original value or range?
Positive feedback mechanisms amplify changes in a system, causing the variable to deviate further from its original value or range. This can lead to destabilization or self-reinforcing processes. Examples include childbirth contractions and forest fires.
How might the emergence of a positive feedback loop affect a system in homeostasis?
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.
What is the phase shift degree of a positive feedback loop?
In a positive feedback loop, the phase shift is typically 0 degrees. This means that the output of the system amplifies the initial input, reinforcing the direction of change. Unlike negative feedback loops, where the output counteracts the input, positive feedback loops enhance the initial signal, leading to exponential growth or rapid changes in the system.
How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
If a response enhances the original stimulus the system is a?
positive feedback system
If a change in the body causes more change in the same direction the system is called?
If a change in the body causes more change in the same direction, the system is called positive feedback. This feedback loop amplifies the initial change and pushes the system further away from its original state.
What is the major difference between positive and negative feedback?
Positive feedback causes bodily processes to continue; negative feedback causes bodily processes to start or stop only cost you being in my basement
What are the two types of homeostasis?
The Negative feedback System & the Positive Feedback System are the two types of Homeostasis
What is example of positive feedback system?

Describing what is feedback system and differentiating between positive and negative feedback?
when a woman's contractions speed up during labor is negative or positive feedback
In a positive feedback system how does the output affect the input?
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.
Which feedback mechanism causes the variable to deviate further and further from its original value or range?
Positive feedback mechanisms amplify changes in a system, causing the variable to deviate further from its original value or range. This can lead to destabilization or self-reinforcing processes. Examples include childbirth contractions and forest fires.
What is a positive feedback mechanism?
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
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.
How might the emergence of a positive feedback loop affect a system in homeostasis?
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.
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.
