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.
Parasitic relation is the ecological relationship that includes parasites living off the host. In this one species gets benefitted while the other gets harmed.
<h3>What is parasitism?</h3>
Parasitism is a type of ecological relationship in which a parasite lives off the host body internally or externally to get benefitted. The host is in harm but the parasite gets benefitted.
The host provides benefits like protection, shelter, food to the parasite living off its body at its own expense. The host can get harmed by the parasite by getting a disease.
Therefore, one organism gets benefitted while the other is harmed.

Well it deepends on how deep you are and what kinds of fossils you find. Like you would find fish, coral, sandallor fossils.
Redone is the least I think
It basically takes out the gene that is responsible for the genetically inherited disease.
