Answer:
The reactivity of acetic acid with various chemicals.
I would have to say Proteins, lipids, and carbohydrates. Carbohydrates being the first energy source, lipids second and lasting the longest, and proteins the third and final source. although you did not give the full question, so i do not know if i can be completely sure.
Athletics would be the easiest choice here
Sports are an active that takes up a lot of different organ systems. When running I use my muscular system and cardiovascular system the most. The cardiovascular system directly controls running because it helps prevent me from getting tired and worn out faster.
Hope this helps :)
