A body's immediate response to something harmful. Like when you touch a hot pan, you immediately jerk your hand back.
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
In general, negative feedback systems are more common in nature because they work to regulate an animal's bodily systems. When an undesirable process is occurring within the body, a negative feedback loop will reverse the un-beneficial effects of this process by limiting it from continuing on. Positive feedback systems promote the continuation of processes, which can lead to harmful effects for the animal (with exceptions).
The most common controlling mechanism of hormone secretion is a feedback system or circuit. An example of this is body temperature, a condition that is continuously monitored and adjusted as necessary so that the body can function properly.
The ecosystem should have, in general, effective negative feedback relations between it's elements. For instance, a simplest ecosystem "predator-prey-limit" possess 1 negative feedback relation: 1. The more predators are, the less prey is. The less predators are, the more prey is. The other relation in this system is positive feedback: 2. The more prey is, the more predators are. The less prey is, the less predators are. If there would be no negative feedback relation (1), then population of both predators and prey would reach ecosystem limit (alimentary and/or area) and then extinct. rowlat@gmail.com
enzymes situated at key steps in metabolic pathways are modulated by allosteric effectors these effectors are usually produced elsewhere in the pathway effectors may be feed-forward activators or feedback inhibitors kinetics are sigmoid ("S-shaped")
A negative feedback will stabilize an amplifiers positive feed back will force the amplifier to either saturated state. this will hold true for a system too. A more general answer follows. 1. Feedback: Getting information about what just happened and responding to it. 2. Negative Feedback: The response lessens the output. 3. Positive Feedback: The response increases the output.

Feedback in general is the process in which changing one quantity changes a second quantity, and the change in the second quantity in turn changes the first.Positive feedback amplifies the change in the first quantity while negative feedback reduces it.....
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.

Yes
A general explanation of a set of observations or facts is typically referred to as a theory or a hypothesis. It is a proposed explanation that can be tested and further refined through scientific methods and research.

It is when the body responds by going in the opposite direction of the variable that is changing in the body like temperature in order to maintain homeostasis.
