What are the two types of feedback mechanisms?
they are positive feedback and increase activity negative feedback.
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.
What are the feedback mechanisms that regulate hormone levels in the body?
Positive and negative feedback
What are the two feedbacks of Mechanisms?
they are positive feedback and increase activity negative feedback.
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.
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative 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.

Is hemostasis a positive feedback?
Hemostasis involves both positive and negative feedback mechanisms, but it can be primarily characterized as a positive feedback process. When a blood vessel is injured, platelets adhere to the site and release signaling molecules that attract more platelets, amplifying the response until a clot is formed. This cascade continues until the bleeding is effectively stopped, demonstrating the positive feedback nature of hemostasis. However, once the clot is formed, negative feedback mechanisms help regulate and eventually dissolve the clot to restore normal blood flow.
Mechanisms that enhance or drive change are known as?
positive feedback mechanisms
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.
