How do your muscles continue to get energy during high levels of activity when there is not enough oxygen?

The muscles continue to get enough energy during high levels of activity when there is not enough oxygen through the absorption of water. This is why we drink a lot of water before and during hard exercise. I hope this helps! :)

well we can't tell you because we cant see the time give a screen shot or something.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
