Answer:
1. A feedback loop are important because they allow the body to maintain homeostasis
2. Stimulus, sensor, control center, and effector.
3. Positive feedback loops increase changed, this also tends to make a system less stable.
Negative feedback loops tend to buffer changes, this tends to make a system hold it's equilibrium and stay stable.
4. Positive feedback loops speed up the direction of change directing the way to increased hormone concentrations, normally causing a state that moves farther away from homeostasis
5.The bod will change the current condition to adapt and conform to the current situation like sweating.
6. A positive feedback loop amplifies or makes something happen quicker, an example is the regulation of blood glucose levels and osmoregulation.
A negative feedback loop is a reaction that causes a decrease in function like blood sugar regulation, insulin lowers blood glucose when levels are high; glucagon raises blood glucose when levels are low
Hope this helps =)
