ing statements accurately describes specific bacterial cell walls? Gram-negative bacterial cell walls contain teichoic acids, whereas the cell walls of gram-positive bacteria do not. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins. In bacteria with acid-fast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides.
In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins. This statement accurately describes specific bacterial cell walls.
Explanation:
The Gram- negative bacteria constitute of an outer membrane which is richly made up of lipopolysaccharides, phopholipids and proteins. The lipopolysaccharides function mainly as a virulence factor and are involved in causing variety of diseases in animals.
Gram- negative bacteria can be seperated from gram- positive bacteria mainly because of the thickness of peptidoglycan and by the presence of the outer membrane of Gram- negative bacteria. The outer membrane is absent in Gram- positive bacteria.
Answer: Photosynthesis uses the energy obtained from light to free electrons from the chlorophyll pigments that collect the light. In cellular respiration the electron transport chain occurs after glucose has already been broken down.
<span>Amoebas are able to protect themselves from unfavorable conditions by forming a "cyst." An amoeba is type of organism that has the ability to change its shape. The reason for this is for the reason of extending and retracting pseudopods.</span>
