An element
Explanation:

Answer:
D. there is less structural carbohydrate.
Explanation:
Most bacterial cells have a cell wall located outside the plasma membrane, formed by peptideoglycan or murein, which provides protection and shape to the cell. In addition to the wall, some bacteria have a polysaccharide capsule that surrounds this structure, this capsule is a carbohydrate envelope that can allow more or less flexibility to the bacterial cell. The more structural carbohydrates the polysaccharide capsule has the less flexible the bacteria will be. Thus, we can say that if E. coli has the most flexible cell envelope, compared to the envelope of other bacteria, it is because there is less structural carbohydrate in the E. coli envelope.
