The solubility of the solutes is the same at all points in the chromatography process. The solutes are clustered together at the beginning (at the solvent front) because none of them has moved very far yet. The reason for the separation of the solutes isn't that they become less soluble, it's that the solutes are moving at different speeds, like cars in an ...

The energy transfer is achieved by a process called "resonance energy transfer". It needs the positioning of the donor and the acceptor in very close proximity to each other - the light harvesting complexes are optimized for this. This allows the collection of small amounts of light energy and still enables photosynthesis. The figure shows how this works ...

Some of the water that's split is regenerated when the hydroxyl radicals (reactive oxygen species) are converted to hydrogen peroxide, water, etc. by superoxide dismutases and antioxidative mechanisms in the chloroplast (peroxisomes/catalases, etc. take care of this). There's also some evidence that the presence of mannitol, ascorbate and glutathione protect ...

Single covalent bond is a shared pair of electrons. For stable bond there should be 2 atoms with unfilled higher orbitals and at least a pair of electrons that is "distributed" among those slots. UC Davis have hilarious page on that.

So refer to the following diagram, In the photosystem II complex, water is decomposed into oxygen and protons. That's two electrons liberated from each water molecule. Plastoquinone accepts two protons from the stroma by coupling it to the two electrons it receives from the photosystem complex. In this manner, the protons are transported to the lumen, and ...

I am going to play the devil's advocate here. I don't know if working out within the first three hours of waking is necessarily the best time to do so. In the morning, we have what is called cortisol awakening response which is where the body releases cortisol. Cortisol is a by product of the sympathetic nervous nervous system. Dr.s James E. Muller, ...
