Your body burns fuel to get the energy it needs to function. Just like any other combustion process, this generates heat. Since metabolism happens constantly, your body constantly generates heat.\n\nIn order to keep a constant temperature, your body has to balance heat production against heat loss. It turns out that this is easiest when the air temperature is less than your body temperature, since you will lose excess heat to the air. That's why around 75F (25C) tends to be comfortable for most people.\n\nIf the air temperature is the same as body temperature, you can only loose metablic heat through the evaporative cooling provided by sweating. This isn't as effective a process, so temperatures near body temperature aren't generally comfortable. \n\nIn fact, if the temperature is enough hotter than body temperature, sweating is no longer sufficient to maintain your internal temperature. As a result, the heat quickly becomes fatal.

hormones bind to receptors.  Cells which have the appropriate receptors to which the hormone binds will be responsive.  The answer is C.

The higher the amount of insulin, the greater the amount of glucose receptors that most cells will have.  This means the cells will take in more glucose and reduce blood glucose levels.  This is up to a certain point, though.  If too much insulin is present, the cells will downregulate their glucose importers and actually take in less glucose.

What kind of receptors? Since different receptors have different functions in the body the area that needs the particaulr role of that receptor will have many more of that receptor than a part of the body that does not need that function.

It's a reflex, a defence mechanism, in order to protect your lungs from taking in foul air for too long and polluting the air circulation system inside you! And then, also to protect your stomach from foul intake, as the smell induces puking and prevents you from eating the foul stuff! The Brain 'impressions' and the Mind reflexes together work towards safeguarding the Biology in you!

Low electric potentials pass all over your body to keep the heart,nerves,muscles,blood healthy and to keep you alive.E.C.G.,electro neuranogram,electro retinogram,electromyogram ,ESR(erythrocyte sedimentation rate)and Electro encephalogram are useful diagnostic tools which measure electrical potentials in your body.The danger is only from high voltage alternate current outside your body.

The endocrine system is all about hormones, and the nervous system coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions.

Homeostasis \nHomeostasis is the physiological process by which the internal systems of the body (e.g. blood pressure, body temperature, acid-base balance) are maintained at equilibrium despite variations in the external conditions. \nThe body can maintain the fluid levels using the kidneys, these organs filter out harmful chemicals and excess liquid into the bladder from which the urine is then expelled.  Body temperature is regulated somewhat by the skin, example, if you are hot you begin to sweat and this helps to cool the body, if you are cold you shiver this helps to raise, the body temperature.
