An observed consequence of higher water vapor concentrations is the increased frequency of intense precipitation events, mainly over land areas. ... Furthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow.
The above statement is true.
The operation of nuclear power plants in the United States is closely monitored and regulated. The NRC or Nuclear regulatory commission is the body that is tasked to monitor and regulate the construction and operation of nuclear power plants. Nuclear power plants use the heat generated from nuclear fission in a contained environment to convert water to steam, which powers generate to produce electricity.

potassium</h2>
Explanation:
The heartbeats of the heart are controlled by the sinoatrial node also known as the pacemaker of the heart. The impulse is generated in the conducting cells of the pacemaker as a result of the movement of sodium, potassium and calcium ions.
The sodium channels allow the movement of sodium into the cell which depolarizes the membrane from -60mv to -40 mv. At this point, the calcium gated channels open which allow the entry of the calcium in the cell which depolarizes the cell up to +5mv.
At this point, the potassium channels open which allows the potassium ions to move out of the cell. This repolarizes the cell and hence the cycle again begins. Reducing the permeability of the potassium ions help generate the autorhythmicity due to repolarization and thus is the correct answer.
