Answer:
Option A
Explanation:
Please see the attachment
Glycolysis occurs in the cytoplasm of the cell. You can remember this because even prokaryotic cells can do glycolysis so it must occur without a membrane bound organelle such as a mitochondrion.
Hope this helps
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:
The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.
Answer:
Option-4
Explanation:
In the given question, S. alterniflora grows in the seaward marsh whereas S. patensis grows in the high marsh. When S. alterniflora is removed, the S. patensis grows to a smaller portion whereas if S. patensis is removed, the S. alterniflora covers all the land.
This shows that although both are different species but they share a niche and the marsh land is the fundamental niche of the S. alterniflora as it can grow in all parts and therefore its distribution is limited by only a realised niche.
Thus, Option-4 is correct.
