HELLPPP I asked this multiple times can sum1 please help:((( Which of the following is the MOST common source of indoor air pollutants in less-developed countries?

A. poorly ventilated cooking fires
B. carbon monoxide from vehicles
C. cleaning solvents
D. air-conditioning units

I think it's A. poorly ventilated cooking fires.

I hope you get it right!

then that particular organisms become extinct.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
