<u>ANSWER:</u>

The correct option is: A. "Archaea lack peptidoglycan" in the walls of the cell. Peptidoglycan is a polymer of sugar and amino acids which forms a layer around the "plasma membrane" of bacteria.

<u>EXPLANATION:</u>

  • This however does not mean that archaea lack cell wall. Archaea have cell walls that are similar to gram negative bacterial cell walls.
  • Archaea are species that give a negative response to gran staining technique. Therefore, there are no gram positive archaea species. The cells walls in archaea may be of several different types of cell walls.

Answer: A

Explanation:   Archaea possess a broader range of cell envelope structural formats than eubacteria and their cell walls do not contain peptidoglycan. Some archaea have only a single S-layer as their cell wall  whereas others have multiple layers.

babunello [35]
If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight, the object will remain suspended at that depth.
