Answer:  Smog

A primary air pollutant can be defined as a pollutant which is released directly into the air from the source of it's origin. It includes gases like sulphur dioxide, ammonia, particulate matter, volatile organic matter, nitrogen oxides and carbon monoxide.  A secondary air pollutant is a pollutant that is not directly released from a source into the atmosphere, instead it can be defined as aggregation of primary pollutants with the atmospheric gases.

Smog is an example of secondary pollutant, it cannot be included in the primary pollutants. It is formed by combination of primary pollutant with oxygen, water and hydrocarbon present in the atmosphere.

zvonat [6]

Stonefly larvae, for example, are very sensitive to polluted water and low dissolved oxygen. You collect a lot of stonefly larvae in your study of a local stream and conclude that this stream has high levels of dissolved oxygen and is minimally polluted. Your conclusion is an example of deductive reasoning.

  • In both science and daily life, deductive reasoning is a sort of deduction. It occurs when you combine two genuine premises to arrive at a conclusion.
  • As an illustration, A = B. B and C are also equal. Deductive reasoning allows you to draw the conclusion that A and C are equal given those two statements.
  • Every dolphin is a mammal, Every mammal possesses kidneys.
  • You can draw the conclusion that all dolphins have kidneys through deductive reasoning. Keep in mind that for this to function, both assertions must be true.
