If you exercise with enough intensity that the blood ph is changed, you have exceeded the
select one:
a. aerobic threshold
b. acidity point
c. base point
d. ph threshold
e. anaerobic threshold

The correct answer is; e. anaerobic threshold  

Explanation:

The Anaerobic Threshold (also called Lactate Threshold) is a period during exercise in which there is increased buildup of lactic acid levels within the muscles. This mechanism usually occurs when exercising with increased intensity during which anaerobic energy is highly produced than aerobic processes. This physiological mechanism causes an increase in the acidity of the muscle cells and influences the blood PH along with other metabolites in the body.

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.

yes it is   dangerous

because that foot is discusting and could get you sick
