Although bacteria can be seen without staining, not all of their characteristics can be visible. Thus, with staining one can see if the bacteria is gram positive or negative, the outer wall's or capsule's structure, the exact size and texture of the surface etc. Without staining, it would be very difficult if not impossible to differentiate between different bacteria types.
Fixing a bacteria allows the scientist to immobilize and preserve it. Thus a complex study can be performed over a longer period of time. The bacteria can also be preserved in order to be restudied at a later date.
The rapid depolarization phase of the action potentials of myocardial contractile cells is due to Na⁺ ion.
The depolarization is caused when Na⁺ ions rapidly enters into neuron through open sodium channels. Sodium ions plays important role in various physiological process such as regulating blood volume, ph regulation, maintaining blood pressure, energy metabolism,osmotic equilibrium, excitation-contraction coupling, maintenance of cellular homeostasis, development and growth.
