The least prevalent gas in the atmosphere was oxygen several billion years ago. This is because it was only around 2.4-3 billion years ago when the first photosynthetic bacteria evolved, meaning they produce food from inorganic compounds such as carbon dioxide and water to produce glucose and oxygen. Oxygen is then released in the atmosphere and this is called <em>The Great Oxygenation Event</em>.
Potassium is fundamental for neuron activity. If a body does not have enough potassium, then the neuron will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.
The potassium (K+) is maintained at a high level within the neuron at rest, whereas sodium (Na+) is maintained at a high level outside of the cell.
Neurons contain K+ and Na+ leakage channels that allow the two ions to diffuse in favor of a concentration gradient.
Depolarization opens both K+ and Na+ channels in the membrane, thereby these ions can flow out and into the axon, respectively.

Explanation:
What is motion? define friction.
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
