No, a hydrogen ions separates.
H2O --> H+ + OH-
Oxygen go in the atmosphere.
Oxygen is one of the most electronegative elements in the biological world. This electronegativity is needed on the end of the electron transport chain. Electrons are passed from one complex or cytochrome to the next, and each successive molecule to be reduced needs to have a greater attraction for electrons than the last. So the end molecule, oxygen, needs to be electronegative enough to pull those electrons away, split and bond with two hydrogens to form water.
a molecule with polar and nonpolar end
No, not at all. Most fish extract the oxygen that is dissolved in the water, not the oxygen that is bound to hydrogen in the formation of water. This is one reason that most aquariums have an aerator bubbling away - it is adding oxygen to be dissolved by the water.
Phosphorus to keep oxygen away from it so that it does not get oxidised
Primarily the erosive power of wind and water. Rivers and rain will wear away even the hardest stone.
Oxygen atoms are highly electronegative and pull electrons away from the electropositive hydrogen atom.
It is possible to change water into another form. H20 may be changed into other forms through chemcial reactions. A process known as electrolysis breaks water into Hydrogen and Oxygen.
an example would be an O2 that meets water. The electrons in the O2 molecule all move to the opposite side of each atom, away from the negatively charged Oxygen in H2O, thus leaving a slightly negative charge on the side away from the H2O molecule and a slightly positive charge towards the H2O molecule. The positive attract the negative electrons in the water.
take oxygen and water in cup the mix it and take oxygen in hand and threw it away
Probably the most hydrophobic molecule is the cholesterol molecule. It is composed mostly of fat and therefore will move away when exposed to water,

No. We cannot get oxygen from water. The oxygen that forms part of the water itself is locked away in H2O molecules and our bodies have no way of extracting it. Most water does contain dissolved oxygen, but since we do not have gills we cannot extract that either.
There are two parts to the phospholipid molecule. One is a hydrophobic hydrocarbon chain, which points away from water. The other is a hydrophilic phosphate ionic group, often represented as the "head" of the molecule, which points towards water.
It's polar because the oxygen molecule is more electronegative than both the hydrogen atoms together. This means that the oxygen atom attracts the electron of each hydrogen more strongly than the hydrogens, so the electrons spend more time around the oxygen. Since a hydrogen by itself is neutral, when its electron (negative) is pulled away it becomes (partially) positive. And the oxygen, having more of the electron, becomes more negative. So you now have a molecule with an area of negative charge (the oxygen) and an area of positive charge (the hydrogens). This positive/negative charge within the molecule makes it polar.
