Q:

Which one of the following air pollutants combines with the haemoglobin of human blood and reduces its oxygen-carrying capacity, leading to suffocation and may cause even death?

A) Chlorofluorocarbon	B) Fly ash
C) Carbon monoxide	D) Sulphur dioxide

Answer & Explanation Answer: C) Carbon monoxide

Explanation:

Carbon monoxide (CO) is very dangerous because it binds with the haemoglobin more efficiently than oxygen does. It "hogs the seats" so that oxygen can't get a ride. And those CO molecules keep riding around, never giving their seats up to the oxygen. This means there is no way to get oxygen to the brain, heart, or other cells and those cells start to die. And finally, it leads to suffocation and even death of a person.

Answer & Explanation Answer: A) Amphibian

Given their complex life cycles and other traits, amphibians are often recognized as indicators of ecosystem health.
