Rotate a coil of copper wire between two magnets.
Multicellurar life would end with the current generation.
what would most be likely happen if green plant were exposed to longer days in sunlight
If glycolysis could not happen in a cell, the cell would not produce ATP molecules.
then all the dead stuff in the garden would stay and would not decompose, it would stay right there and nothing would happen to it, nothing would eat it away. fungi and decomposers eat dead organisms.
Amino Acids
to produce a continuous psource of electirc current, you would need electrons.
They're both true, but I'm not comfortable with the way they're stated. I would have said: -- Electric current through a wire produces magnetic force. -- Moving electrons constitute an electric current, whether or not they're moing througha magnetic field.
I presume you mean what do you measure electric current with. You would use an ammeter.
Since Electric Motors are not 100%, you could say that they produce "waste". I believe that the majority of that "waste" would be in the form of heat. Part of that heat is lost in the windings and is proportional to the square of the current, and part of it would be friction loss in the bearings. Electric motors are typically better than 90% efficient.
Electric current produce magnetic fields. However, in the case of AC (alternating current, usual in households), the current changes so quickly (and the current has an average value of zero) that I am not sure the effect on a compass would be visible to the naked eye.Electric current produce magnetic fields.

He found that certain materials would produce small amounts of electric current when exposed to light occasionally.
For the United States of America your keyboard configuration would be "English (United States) - US". I belive the modern configuration is (QWERTY)
No, an example of an electric current would be using a battery to light a lightbulb.

I will attempt to answer the question I think your asking: 'If an electric generator produces an electric current due to magnetic induction, then why isn't a current produced via the same mechanism in an electric motor?' The answer to the best of my understanding is that it is, or at least, it would be. The reason is that in a generator a conducting wire is rotated in a magnetic field and this induces a current as each charged particle experiences a force as determined by F=q(vxB) [this is the vector form of the equation using the vector product] or F=Bqv if you are unfamiliar with vectors. As this causes electrons to move this manifests itself as an alternating current in a wire. Conversely in a motor and alternating current is passed through a magnetic field in a coil of wire, this time the wire now experiences a force F determined by F=I(lxB). This produces a torque on the centre of the motor and it is this torque that drives the motor. However if you were to rotate the coil of the motor externally without supplying a current to it then the reverse process would take place. This would induce an AC current in the motor which would now function as a generator. As a aside if this current was then driven through the generator it would then rotate exactly as the motor did.
Electric current is both positive and negative. If there were only one of those it would be an open circuit and it would not work. The particles would be able to flow one way but not the other.
