, What compound is found in the cell wall of gran negative not gram positive? -
CORRECT ANSWERS lipopolysaccharide
An acid dye is - CORRECT ANSWERS India Ink
Gram positive cells retain the primary stain whereas gram negative do not
because? - CORRECT ANSWERS - The alcohol removes the outer
membrane and therefore, the trapped from stain gram negative bacteria
- the alcohol shrinks the pores of thick peptidoglycan of gram positive cells
therefore trapping the stain

same ________ of glass. - CORRECT ANSWERS Refracting index
Endospores represent a challenge to the fellas of industrial and medical
microbiology because - CORRECT ANSWERS they are resistant to
harsh environments, allowing survival of spore under conditions where
nonsporing wouldn't survive and they are pathogens.
