The statement above is TRUE, acid rain is a secondary pollutant.
There are two basic types of pollutants, these are primary and secondary pollutants. The primary pollutants refer to those pollutants that are directly emitted from their sources. Examples are ammonia and carbon monoxide. Secondary pollutants on the other hand refer to those pollutants that are formed from the reaction of primary pollutants in the atmosphere. An example of secondary pollutant is acid rain, which forms as a result of reaction of sulphur dioxide and nitrogen in the atmosphere.
Acid rain is a secondary pollutant resulting from the reaction between sulfur dioxide and nitrogen oxides, primary pollutants, with water, oxygen, and other substances in the atmosphere. The resulting acid rain has a severe impact on both natural ecosystems and manmade structures. Despite regulations, it continues to be a significant issue in some industrial regions.
Yes, acid rain is indeed a secondary pollutant. It is caused when sulfur dioxide and nitrogen oxides, primary pollutants released from industrial processes and fossil fuel combustion, react with water, oxygen, and other substances in the atmosphere to form sulfuric and nitric acids. These acids then fall to the ground as acid rain. Acid rain is characterized by its acidity, having a pH of less than 5.
Acid rain has been a severe problem in industrial areas, particularly in North America and Europe until the 1980s. The acidity of this rain has led to the destruction of forests, damage to soil, and transformed freshwater lakes into an inhabitable environment for only the most acid-tolerant species. Acid rain also significantly corrodes marble and limestone structures. Regulatory interventions limiting the emission of sulfur and nitrogen oxide have reduced the severity of acid rain, but it remains a growing problem in areas like China and India.
The impact of acid rain on both natural and manmade environments is profound. It not only destroys the natural landscape and aquatic ecosystems but also causes the degradation of buildings and monuments, as seen in the case of the Lincoln Memorial in Washington, DC.

Enzymes and inorganic compounds are used to carry out chemical reactions and regulate metabolism in organisms.
The compounds used to carry out chemical reactions and regulate metabolism in organisms are enzymes and inorganic compounds.
Enzymes are catalytic proteins that speed up chemical reactions in the body, including the breakdown of food and the conversion of energy. Inorganic compounds essential to human functioning include water, salts, acids, and bases, which play important roles in maintaining homeostasis and osmotic balance.

Answer:
the answer is trisomy
Explanation:
A usual heart rate in case of adults varies from 60 to 100 beats per minute. Usually, a lower heart rate at rest signifies more effective functioning of heart and better cardiovascular fitness. For example, a well-trained athlete may possess a usual resting heart rate closer to 40 beats in a minute.
The following is the correct order to measure the heart rate:
1. Make a fist.
2. Find a radial artery.
3. Feel a pulse.
4. Count for 10 seconds.
5. Multiply by 6.
