You would revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.
<h3>What is pH?</h3>
pH may be defined as the power of hydrogen. It determines the acidity or basicity (alkalinity) of any substances under any temperature or pressure.
The role of human activity affects the overall consequences of oceans to a larger extent.
Therefore, you would revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.

Answer: Option D.
The lub heart sound is due to the closing of atrioventricular valves.
Explanation:
Heart sounds are noises that are generated from beatings from heart and from blood that flows through it. The heart sound reflect the turbulence generated when the heart valves snap shut. Lub is the first heart sound also called S1 and it is caused by turbulence and closure of the atrioventricular valves(mitral and triscupid valves) at the start of systole. The second sound is the dub sound which caused by the closing of aortic and pulmonic valves at the end of systole.
