Anatomy is the best answer
The urban areas are more likely to have smog than the rural areas.
Urban area can be referred to as the town or city with advances an developments. Since the urban areas have more population density, more electronic items, vehicles and also industries, that is the reason why they are more likely to produce the smog or any other form of pollution.
Smog is a type of air pollution formed dye to the combination of smoke and fog. The most common source of smog is the burning of coal. This can be either due to industries or the fuels of vehicles. Fog can be of two types: Photochemical smog and industrial smog.

Question: Why do organisms without oxygen need to convert pyruvate to lactate?
A) because pyruvate is toxic to the cells
B) in order to regenerate NAD+
C) in order to use lactate in the citric acid cycle
D) because lactate is needed to produce ATP
Answer:
B) in order to regenerate NAD+
Explanation:
Kreb's cycle and electron transport chain (ETC) are the aerobic stages of cellular respiration. ETC regenerates NAD+ and FAD+ by oxidation of NADH and FADH2 produced during glycolysis and Kreb's cycle. Here, oxygen serves as the terminal electron acceptor.
Glycolytic reactions use NAD+ as an electron acceptor and produce NADH. Therefore, a constant supply of NAD+ is required to sustain glycolysis. In absence of oxygen, ETC cannot occur and organisms convert pyruvate into lactate. Pyruvate is reduced in lactate and NADH serves as the electron donor. Thereby, lactate fermentation regenerates NAD+ to continue the process of glycolysis.
