Sorry I have a slow mind... What word do weather forecasters use to describe water vapor that has gathered in a cloud?

answer; ///(statins)/aka as hmg coa

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
