Electrons

Electrons

stable elementary particles having the smallest known negative charge, present in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons around atomic nuclei determine the chemical identities of elements. Beams of electrons are called cathode rays or beta rays, the latter being a high-energy biproduct of nuclear decay.

Is there any difference between different fertilizers?

... both sources. For example, whether nitrogen from organic or chemical fertilizer contains nitrogen atoms with same number of protons, neutrons and electrons. I think food produced by using organic and chemical fertilizer is almost same if we avoid the usage of harmful pesticides. Only using organic ...

Electron transport chain

The electrons are passed through molecules in the membrane, so the oxygen is not much accessible to them.

Electron transport chain

Electrons are finally accepted by oxygen at the end of the electron transport chain. Is oxygen is accessible to the electrons in intermediate electron carriers? If so why electron is not accepted by oxygen at intermediate ...

Re: Is complexity inevitable?

... I don't know if we're certain of indeterminacy, or if indeterminacy is merely what is suggested by the apparent randomness of small particles like electrons (and photons :?: ). But back to biology . Have you considered that the human niche is actually a collection of niches? Most organisms cannot ...
