Answer 1

Blood, cell interior, digestive fluid

Step-by-step explanation:

The lower the number the more acidic the substance. The question asks least acidic (highest number) to most acidic (lowest number), so we need to list these from the highest pH to the lowest pH. That means blood (7.3), then cell interior (6.8), and finally digestive fluid (2).

Answer 2

C. blood, cell interior, digestive fluid

Step-by-step explanation:

least acidic is 7.3 and most acidic is 2
