The digestive works to break down food eaten before exercising.
The digestive system is responsible for the process of digestion, which involves the breaking down of the consumed food into smaller parts which can be absorbed by the body. This system is comprised of the gastrointestinal tract and several organs participating in digestion, which are the tongue, salivary glands, pancreas, liver, and gallbladder.
The circulatory takes in the nutrients obtained from the food.
The circulatory system (also known as cardiovascular system) is responsible for circulating blood through the body and transporting nutrients and many other chemicals. The heart and the lungs are two critical components of this system since blood flows through the lungs and oxygenates. This oxygenated blood is pumped through the heart to the rest of the body.
The body sweats as a mechanism to cool off, because the excretory is working to flush out toxins.
The excretory system is responsible for removing excess and unnecessary materials from the body fluids of an organism. The main organ system involved in this system is urinary system, however, excretion is also achieved through breathing and sweating.

Answer:
In acid-fast staining, carbon fuchsin is used as a primary stain which dissolves the mycolic acid present in the cell wall of <em>Mycobacterium smegmatis </em>and penetrates through it which results in staining <em>Mycobacterium</em> red.
Staphylococcus aureus cell wall does not contain mycolic acid so carbon fuchsin does not penetrate its cell wall, therefore, it becomes colorless after destaining with acid alcohol.
After destaining step methylene blue is added to stain non-acid-fast bacteria blue. So if I mistakenly forgot to use methylene blue during the procedure <em>Mycobacterium smegmatis</em> will appear red due to carbon fuchsin present in their cell wall and S<em>taphylococcus aureus</em> will appear colorless because it is destained.
