Answer:
c) Neutral
The pH human blood falls within a neutral range that is near a pH of 7.4.
Step-by-step explanation:
The pH measures acidity or alkalinity levels of something. e.g. water, blood, stomach.
The pH levels range from 0 to 14. A pH level close to 0 is strongly acidic while, a pH level close to 14 is strongly alkaline. Human blood is near a pH level of 7.4 which means it is slightly alkaline, although very close to the neutral pH level reading of 7.0. Thus, pH human blood falls within a neutral range.
