The lower boundary of the exosphere is called the exobase. It is also called exopause and 'critical altitude' as this is the altitude where barometric conditions no longer apply. Atmospheric temperature becomes nearly a constant above this altitude.
Sodium â the volatility and solvent mineral: essential to life, all body fluids contain sodium â itâs needed for many biochemical processes including water balance regulation, fluid distribution on either side of the cell walls, muscle contraction and expansion, nerve stimulation and acid-alkaline balance.
Magnesium, potassium and calcium are minerals that your body needs to maintain strong bones and normal muscle function. They are all electrolytes, or minerals that conduct electrical impulses in your body.These minerals help to maintain fluid balance, nerve transmissions and a healthy blood pressure.Magnesium also helps transport both calcium and potassium across cell membranes.
