The pacific ocean has the tropical maritime air mass so it is warm and wet. they affect the United States originate over the Caribbean sea, Mexico, pacific and the western Brazil.
So the air masses in the pacific ocean, western Brazil are wet and warm.the air masses have the fairly uniform temperature and the moisture content in the horizontal direction.

When the cardiac muscle cell is at rest, the concentration of sodium and calcium is greater on the outside of the cell.
The resting membrane potential (the cardiac muscle cell is at rest) is characterized by more negatively charged inside of the membrane comparing to the outside. The main ions found outside the cell at rest are: sodium (Na+), and chloride (Cl−), and Ca2+ whereas inside the cell it is mainly potassium (K+).
