Why is positive feedback in blood clotting but unsuitable for the regulation of body temperature?

The human body has two type of feedback mechanism, positive and negative feedback. Positive feedback is a cyclic process that amplifies the action of a system until a negative feedback response is obtained. Positive feed back is important in processes that must go to completion quickly, for instance blood clotting. But it is harmful in situations in which stable conditions must be maintained, for instance body temperature,  this is because it encourages departure from the state of stability. 

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
