Answer 1

Answer:

C. blood, cell interior, digestive fluid

least acidic is 7.3 and most acidic is 2

Answer 2

Answer:

Blood, cell interior, digestive fluid

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).
