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.
The difference in an area with high concentration and an area with low concentration is called concentration gradient.
<h3>What is concentration gradient?</h3>
Concentration gradient refers to the difference between the concentrations of two solutes in a solution.
A solution usually contains an area or region with higher concentration and an area with lower concentration.
The difference between these two areas of different concentrations is referred to as a concentration gradient.

Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
I believe the correct answer to this question would be:

Hydrothermal vents are usually located on the most bottom
part of the ocean. A hydrothermal is created when there is a fissure in the
planet’s surface underneath the ocean.
