How does high altitude affect breathing? please help

the air at higher altitudes is colder, less dense, & containsa lot less oxygen molecules. which means that you need to take more breaths than lower altitudes

Please mark brainlist!

*and rate & say thanks!

Per my research, it was said that the higher the elevation, the more difficult breathing becomes. The air at higher altitudes is colder, less dense, and contains fewer oxygen molecules, which means that you would need to take more breaths in order to get the same amount of oxygen as you would at lower altitudes.

Hope this helped and please correct me if I am wrong. I did my research and I think this is right because of the elevation. Have a good one!

the sphincter muscles at the end of the digestive tract is the anus.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
