The dependent variable is the growth of the bacteria
True, extreme weather events, sea level arise
Temperature, Nutrients, dissolved oxygen and the pH. A high pH and temp increase the size of plankton
What do the Gram stain, acid-fast stain, and endospore stain have in common?
A. used on a wet mount of the specimen
B. use heat to force the dye into cell structures
C. outcome based on cell wall differences
D. use a negative stain technique
E. are simple stains
Answer: Option C
Explanation:
The staining can be defined as a procedure which is carried out in order to make the study easy. As many of the bacterial species appear similar and are transparent so staining is done in order to see what bacterial species incorporates what color in them to make the study more easy.
Staining also depends on the type of chemicals present in the cell wall of the organism( cell wall composition). Different organisms have different staining techniques and stains by which they show color.
This ability tells alot about their characters. Like the fast stain bacteria are very hard to stain. They are mycobacterium on which normal stain do leaves any effect because of the cell wall composition. This property states that they are resistant to many of the chemicals . Likewise gram staining and endospore staining is also dependent on the type of chemical that is found in their cell wall.
