Taste: There are 5 basic tastes that the human tongue can detect. They are sweet, savory, salty, sour and bitter. These are detected by taste receptor cells on our tongue, I won't go deep into the biology part. The basic tastes of sweet, salty and sour have different thresholds, or concentration levels, at which they can be detected. In other words, it is ...

Taste and smell are mediated by receptors in your body that molecules can attach to. These receptors then give off an electrical signal which is translated in the brain to a certain taste or smell. The details of this are biological and not of importance here. So no, there is no relevant frequency or even wave-like behavior. Touch is a very different thing. ...

It depends on what exactly you mean by electricity. When you're thinking about electricity moving this could be an electric current, or it could be an electric field. The obvious example of the first is current flowing in a wire, and the obvious example of the second is a radio wave travelling (at the speed of light) between the transmitter and your radio. ...

I found out that they mention about whole ions being moved in the human nervous system in order to transfer an electric impulse Electric impulse I think u mean signal. Take look on Action potential there picture demonstrates moving of signal. So neural signals are not current itself, or moving ions from head of neuron to his tail(transferring ...

The key to electricity is that it is moving charge. In our electrical wires we use electrons, which carry charge, to send signals. The current is the net flow of charge through a wire (or whatever is carrying the current) which then depends on the speed. The speeds at which electrons move involve a few distinctions. Firstly, the electrons move randomly due ...
