What is the difference between positive and negative feedback cycles?
Most of our bodies systems run on negative feedback. This means, for example, say you are hungry. Your body produces and releases a signal and when you are fed, your body realizes it needs to stop making you feel hungry. So other hormones/signals are released to quiet down the initial one. Very few of ourbodies systems run on positive feedback. One example is labor contractions. A signal is given in the body to have a small contraction, that contraction happens and instead of the body saying "okay mission accomplished" and quiteig down the first signal (like in negative feedback) it actually INCREASES the amount of the initial signal so you get more and more powerful contractions. Hope I explained that so you understand it!
What is negative feedback in your bodies?
Self-regulating system; information about effect of hormone that is fed back to gland, which then decreases secretion of that hormone; most common method of regulation
How does a negative feedback work in animal bodies?
Negative feedback is something that reduces the output of a system. In animal system it is a decrease in function in response to a stimulus.It brings back a reaction to a set point. For example, your blood sugar has a certain range of values. When you drink or eat something with a lot of sugar in it, your body responds with the hormone insulin to bring the sugar level down towards the normal range.If your sugar level drops too low below the normal level, your body will release another hormone called glucagon. This will bring the level back up toward the normal range.It is a balance act and it is called homeostasis.

Why do human bodies need to regulate between 96ºF and 100ºF?
It is the temperature range at which the cells that make up the body work the most efficiently. Any lower and they can't support the functions necessary to keep the body alive. Any higher and they begin to "cook". Because of homeostasis and negative feedback. if bodies become too hot or too cold the body is unable to function correctly. For example if various enzymes(the catlysts for chemical reactions in the body) are too hot they cease to function in the body. so the body works to maintain a temperature that it can function correctly at and therefore continue running effectively.
Do gymnist have menstrual cycle?
