Question

Give one example of positive feedback mechanism​

Answer 1

Answer:

Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. ... Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.

Explanation:

A good example of a positive feedback system is child birth. During labor, a hormone called oxytocin is released that intensifies and speeds up contractions. ... Another good example of a positive feedback mechanism is blood clotting.

Answer 2

Regulation of kidney function:

When there is excessive loss of fluid from the body or when there is an increase in the blood pressure, the osmoreceptors of the hypothalamus respond by stimulating the neurohypophysis to secrete the Antidiuretic Hormone(ADH) or Vasopressin.

It is an example for positive feedback mechanism.
