An oxidant is also called oxidizing agent, it means it oxidizes other and itself undergoes reduction, a good oxidant will be a good electron acceptor, in order to identify the strong oxidant, we need to see the oxidation state of the element, if the element is in its highest oxidation state then it will act as a strong oxidant, for example, KMnO4, Mn is in +7 oxidation state, which is the highest possible for Mn, similarly, K2Cr2O7 is also a strong oxidizing agent having the highest possible oxidation state of Cr that is +6,

The reductant is also called reducing agent, it means it will be a good electron donor, so in order to be a strong reductant, the element should be in its lowest possible oxidation state, for example, NaH, LiAlH4, NaBH4 are some strong reducing agent, which is strong tendency to donate the electron, metals are generally oxidizing because they are good electron donor.

3) How is it that we all have the same genes, yet we can have different genotypes for a given gene that results in the expression of a different phenotype? This is not the same answer as the previous question. Again, I am looking for a description of what is happening on a molecular level to result in different phenotypes.

If all we can observe are things inside the observable universe, how do we know that anything even exists outside this boundary? I can see four ways of solving this problem. 1) We wait a while, the observable universe should get 'larger', so we should be able to observe more. I don't think this is practical though, since telescopes have only existed for a hundred years or so, whereas the age of the universe is many degrees larger. Also, galaxies...
