WebFeb 20, 2024 · The key difference between positive and negative feedback is your response to change: positive feedback amplifies change, while negative feedback reduces change. This means that positive feedback will result in more products: more apples, more contractions, or more clotted platelets. Negative feedback will result in … WebNegative Feedback Mechanism. It occurs when the original effect of the stimulus is reduced by the output. Negative feedback mechanism normalizes the things when they start becoming too extreme. For eg., the thyroid gland is regulated by a negative feedback mechanism. The hormone secreted by the hypothalamus stimulates the pituitary gland to ...

WebPositive Feedback. Positive feedback involves a response that reinforces the change detected (it functions to amplify the change) A change is detected by a receptor and an effector is activated to induce the same effect – this promotes further change. Positive feedback loops will continue to amplify the initial change until the stimulus is ...
