What else can I help you with?
Do all bacteria have capsules?
No, not all bacteria have capsules. Capsules are a protective layer of polysaccharides or proteins that some bacteria produce around their cell wall. It is a feature found in some bacterial species but is not universal.
What is the name for the protective structure that forms around a human embryo?
The protective structure that forms around a human embryo is called the amniotic sac or amnion. This sac contains amniotic fluid, which cushions and protects the developing embryo during pregnancy.
What had happened to the bacteria in the clear area around the paper disc soaked in spot lotion?
The bacteria in the clear area around the paper disc soaked in the spot lotion were likely killed or inhibited from growing. The spot lotion contains chemicals that are effective against bacteria, creating a zone of inhibition where bacterial growth is suppressed.
What is the name for the protective structure that forms around an embryo?
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
What is a protective structure formed by bacteria?
Capsules. Encapsulated organisms are very tough for the body to resist because they are hiding inside a polysacharide or polypeptide shell that phagocytes do not recognize as foreign pathogens. This also means that most encapsulated bacteria are among the most pathogenic of all. Most capsule formers are responsible for horrific diseases because the body has little resistance against them.
What is a polysaccharide contained in the cell walls?
A Capsule. Capsule- in Mosses, the part that contains spores; in bacteria, a protective layer of polysaccharides around the cell wall.

What is the name for the protective protective structure that forms around an embryo?
Placenta.

Which kingdom is bacteria found in you and around you in?
Ciro bacteria
What barricade is constructed around exposed resources to it from overpressure and fragmentation?
Protective barricade
What is a extracellular bacteria?
Intracellular Bacteria is bacteria that lives inside of a cell such as a macrophage. If the cell knows the bacteria is living inside of it the cell will destroy it, but some times bacteria can not be detected by the cell, so it lives inside of the cell. But how does the body destroy intracellular bacteria? In order for the cell to destroy the intracellular bacteria it needs the assistance of a T-Cell. OK, lets put the cell that contains the intracellular bacteria aside for right now. The T-Cell has previously found a different cell that recognized the virus and destroyed the virus. After the cell destroyed the virus it placed a piece of the virus along with a piece of MHC on the outer wall of itself. The cell is now called a "Presenting Cell". A T-Cell comes along and binds to the presenting cell recognizes that it killed the bacteria and begins to proliferate (divide) into thousands of CD8+ and CD4+ cells. The new CD4+ cells then differentiate or divided in to TH1 or TH2 cells. NOW... as the TH1 cells are moving around our body. The TH1 cells are very good at recognizing cells such as macrophages that have the intracellular bacteria living inside of it. When the TH1 cell find a cell that contains intracellular bacteria, the TH1 cell attaches itself to the cell that contains the intracellular bacteria and reprograms the cell it so it recognizes the intracellular bacteria and then destroys it. What happens after the TH1 cell reprogrammes the cell that contains the intracellular bacteria? The reprogramming allows the lysosomes inside of the cell to recognize the bacteria. The cell then forms a Phagosome around the intracellular bacteria. lysosomes inside of the cell attach the Phagosome creating a Phagolysosome. The Phagolysosome is like a bag that contains the intracellular bacteria and destroys the bacteria though lysosomal enzymes and other toxins. The cell then releases the destroyed bacteria as debris.
When was bacteria invented?
No one "invented" bacteria, bacteria was around billions of years before we were.
What is the chemical composition of bacterial capsule?
It usually consists of polysaccharides,[1] but can be composed of other materials (e.g., polypeptide in B. anthracis). Because most capsules are water soluble[citation needed], they are difficult to stain using standard stains because most stains do not adhere to the capsule. For examination under the microscope, the bacteria and their background are stained darker than the capsule, which doesn't stain. When viewed, bacterial cells as well as the surface they are on, are stained dark, while the capsule remains pale or colorless and appears as a ring around the cell.
What is a. capsid?
A protective shell around a virus
