The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span>  </span>

How is absolute different from a solvent in a solution?
swat32
A simple solution is basically two substances that are evenly mixed together, but the mixture is homogeneous. Meaning, you can no longer tell the two substances apart once they are mixed in solution.
This is because the solute dissolves in the solution.
A solute is the substance to be dissolved (sugar). 
The solvent is the one doing the dissolving (water).
As a rule of thumb, there is usually more solvent than solute.The amount of solute that can be dissolved by the solvent is defined as solubility.
