Answer:
The correct answer is D. A gram-negative cell wall consists of a thin layer of peptidoglycan surrounded by an outer membrane containing lipopolysaccharides.
Explanation:
Gram-negative bacteria are bacteria that do not retain the gentian violet dye during the Gram staining protocol.
During the Gram staining process, a contrast dye, usually safranin, is added after gentian violet, causing the Gram negative bacteria to stain pink or red. The contrast dye thus allows the visualization of Gram-negative bacteria which, because they have a thinner layer of peptidoglycans, cannot retain the gentian violet dye.
Its main feature is an endotoxin called lipopolysaccharide that causes pathogenicity and is responsible for its virulence.
The answer is Muscular Organs
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
