The right answer is D. Annelids.

Annelids are protostomial vermiform organisms measuring between 0.5 mm and 3 m long. They have a body of cylindrical section, with a symmetry bilateral and metamerized, that is to say, which seems composed of a series of identical rings.

Sometimes with teeth or chitinous jaws, the mouth is at the level of the prostomium, the first segment, while the anus is on the pygidium, the last segment. Between the two, the body contains a straight digestive tract and a closed circulatory system.

You INCORRECTLY perform an acid-fast stain on a smear from a mixed culture of Mycobacterium smegmatis (acid-fast) cells and Stap
Dahasolnce [82]

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.
