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.

What 2 processes help organisms achieve homeostasis?
Negative feedback loops and positive feedback loops are two processes that help organisms achieve homeostasis. Negative feedback loops work to maintain a physiological parameter within a set range by reversing any deviation from the set point. Positive feedback loops amplify a response that is already occurring, pushing the system further away from homeostasis before returning to balance.
What is An exponential change away from equilibrium in an attempt to maintain homeostasis?
This process is known as positive feedback. It involves an amplification of a response in the same direction as the initial change, leading to a further deviation from equilibrium. Positive feedback mechanisms are usually temporary and serve to accelerate a process until a certain goal or outcome is achieved.
Is insulin negative feedback or positive feedback?
Insulin is a hormone produced by the beta cells in the pancreatic islets of Langerhans that stimulates glycolysis and increase glucose uptake in muscle and adipose tissue; therefore, it maintain homeostasis in the body by decreasing blood sugar level when it is high. It shows a negative feedback because the response negates the stimulus to maintain homeostasis.
When the body reacts to stop or work in the opposite direction of a stimulus is it known as negative feedback or positive feedback?
When the body reacts to stop or work in the opposite direction of a stimulus, it is known as negative feedback. Negative feedback mechanisms help maintain homeostasis by reducing the effects of a stimulus to keep things within a normal range.
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 would happen if your thermoregulation temperature control used a positive feedback to maintain homeostasis?
you will die
Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
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.
What are the two types of homeostasis?
The Negative feedback System & the Positive Feedback System are the two types of Homeostasis
Are positive feedback and negative feedback both components of homeostasis?
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.
How do feedback on mechanisms help maintain homestsasis?
Feedback mechanisms provide information to the body about changes in internal conditions. This information allows the body to respond and make adjustments to maintain balance and stability, which is essential for overall health and function. By sensing fluctuations and acting to correct them, feedback mechanisms ensure that the body can maintain homeostasis despite external or internal challenges.
Do positive feedback makes homeostasis get out of control?
yes...
What 2 processes help organisms achieve homeostasis?
Negative feedback loops and positive feedback loops are two processes that help organisms achieve homeostasis. Negative feedback loops work to maintain a physiological parameter within a set range by reversing any deviation from the set point. Positive feedback loops amplify a response that is already occurring, pushing the system further away from homeostasis before returning to balance.
Which type of feeback is more common in the body?
Positive feedback loops are less common in the body compared to negative feedback loops. Negative feedback helps maintain homeostasis by reversing a change back to its set point, while positive feedback magnifies a change away from the set point. Examples of positive feedback in the body include childbirth and blood clotting.
What is An exponential change away from equilibrium in an attempt to maintain homeostasis?
This process is known as positive feedback. It involves an amplification of a response in the same direction as the initial change, leading to a further deviation from equilibrium. Positive feedback mechanisms are usually temporary and serve to accelerate a process until a certain goal or outcome is achieved.
Compare and contrast negative and positive feedback mechanisms and give some examples?
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.
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 do feedback mechanisms help an organism maintain homeostasis?
Feedback mechanisms help an organism maintain homeostasis by detecting changes in internal conditions and initiating responses to counteract these changes. Negative feedback loops work to bring the system back to its set point, while positive feedback loops amplify the initial change. Together, these mechanisms help ensure that an organism's internal environment remains stable despite external fluctuations.
