An example of a positive feedback mechanism is blood clotting in which certain clotting factors active other factors until a plug forms to stop bleeding. Is this process involved in homeostasis?
no, positive feedback mechanisms cannot regulate homeostasis
no, it is not a negative feedback mechanism
no, it does not fit into a classic "push-pull" action
no, because it does not result in restoring blood volume
yes, because it is part of a bigger negative feedback mechanism to maintain optimal levels of blood volume.
