The answer would be B, assuming that they're all in the same relative area.
Answer:
The order of bacterial structures that the bacteria would penetrate would be:
- Capsule.
- Lipopolysaccharide Membrane
- peptidoglycan
- Phospholipids Membrane.
Explanation:
A parasite like B. bacteriovorus faces some challenges in getting into a bacterial cell. This is because these cells have devices and strategies to prevent the entry of parasites and ensure the survival of the bacteria. The first challenge would be to penetrate the bacterial capsule. The capsule is a structure that is located around many bacteria. This structure is rigid, with sharp edges and thick thickness, which protects the bacteria from external agents. If B. bacteriovorus manages to go beyond the capsule, it will find a membrane, also thick, composed mainly of lipopolysaccharides, which will also provide protection and try to prevent the entry of the parasite. If this membrane is crossed, B. bacteriovorus will face another layer called peptidoglycan. This layer establishes itself as a cell wall, being very difficult to break. Some bacteria present one more layer after peptidoglycan, which is a membrane made by Phospholipids, which is highly selective and difficult to break, but is more fragile than the previous layers. Only after overcoming all these structures, the parasite will have access to the bacterial cel
The spores produce two types of gametophytes: each microspore develops into a microgametophyte (male gametophyte), which ultimately produces male gametes (sperm), and each megaspore produces a megagametophyte (female gametophyte), which ultimately produces female gametes (eggs).
Compact fluorescent bulbs are a more efficient way to provide electrical light within homes and other buildings. These bulbs are one of the easiest ways to save money. According to GE, compact flourescent bulbs, or CFLs for short, use 70% less energy than a traditional, incandescent bulb and last up to 10 times longer than a standard incandescent bulb. As society pushes for improved efficiency, compact flourescent bulbs need to be carefully examined. Although these bulbs are more efficient, there are many problems with compact fluorescent bulbs.
