How are the graphs of a body chemical controlled by a negative feedback and chemical controlled by positive feedback similar?
Both negative and positive feedback mechanisms in body chemistry involve the regulation of physiological processes through a series of responses that aim to maintain balance or amplify a reaction. In negative feedback, the response reduces the effect of a stimulus, promoting stability and homeostasis, while in positive feedback, the response enhances or accelerates the process, often leading to a specific outcome. Despite their opposite functions, both mechanisms rely on a feedback loop that involves sensors, effectors, and control centers, illustrating the body's complexity in maintaining its internal environment. Ultimately, both types of feedback are essential for the effective regulation of biological systems.

What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
Explain would the formation of a goiter be positive or negative feedback?
Negative.
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.
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor
What are two types of feedback mechanisms found in living organisms?
Positive feedback amplifies a response in the same direction, such as the release of oxytocin during childbirth. Negative feedback regulates a response by counteracting changes, like temperature regulation in the body.
Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
Are hormone concentrations usually controlled by positive feed back?
no by negative feedback
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
Is contractions during childbirth positive or negative feedback?
Positive feedback.
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.
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
What type of feedback system reverses changes in a controlled condition?
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.
What are the two types of feedback mechanisms?
they are positive feedback and increase activity negative feedback.
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 are the two feedbacks of Mechanisms?
they are positive feedback and increase activity negative feedback.
What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
