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.
Answer:
Explanation:
Multicellular orgainism are composed of one of more cells differentiating to take on specialized functions.
Explanation:
Absolute dating is required to determine the relative age of animals based on their fossils. Specific groups of organisms have followed one another in a definite sequence through the Earth's history.
Answer:
Mutualism is where both organisms benefit, commensalism is where one benefits but the other organism isn’t harmed, and lastly, parasitism is where one organism benefits and the other is harmed. The various species found within a single ecosystem can relate to each other in a variety of ways. The terms mutualism, commensalism, parasitism and symbiosis all refer to the various ways that species within an ecosystem can interact with one another.
