Emphysema is a health condition in which the lungs can no longer expel carbon dioxide normally. as a result, a person who has emphysema may have high blood acidity levels. the body process that would attempt to return the blood ph to normal so that cells could function properly is called a. active transport b. adaptation c. homeostasis d. acidosis

The correct answer is homeostasis.

Homeostasis refers to a self-regulating procedure by which biological systems seem to sustain stability while amending the conditions, which are optimal for survival.

This dynamic state of equilibrium refers to the situation of optimal working for the species and involves many variables, like fluid balance and temperature of the body, being maintained within some kind of pre-limits.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
