Answer:
The answer is "Option C".
Explanation:
In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.
- The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood.
- It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.
Answer:
Acid rain is a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. It could cause serious troubles in pollution. Note that acid rain only occurs when near a high power plant do to the high levels of dioxide and nitrogen oxides are released into the air.
Sorry if I miss understood the question or didn't get it right I tried. :)
