What is the toughest of the brain membranes that lies just beneath the skull?
the meninges are 3 membranes that surround and protect the brain and spinal cord, made up of connective tissue.
Is the cell wall of gram positive bacteria thick or thin?
The cell wall of gram positive bacteria is thick.
Bacteria that produce thick walls around themselves are called?
Bacteria that produce thick walls around themselves are called Gram-positive bacteria. These bacteria have a thick peptidoglycan layer in their cell wall that retains the purple stain in the Gram staining technique. This thick wall provides structural support and protection to the bacterial cell.
What is the difference between r and s bacteria?
R bacteria have a rough appearance due to the presence of a sugar capsule on their outer surface, making them resistant to the immune system. S bacteria are smooth in appearance and lack the protective capsule, making them vulnerable to the immune system. This difference in structure affects the virulence and pathogenicity of the bacteria.
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.

Why digestive acid cannot digest stomach?
The inner lining of the stomach is coated in a thick layer of protective mucus that prevents powerful digestive acids and enzymes from damaging the organ. The stomach walls themselves are thick membranes that are similarly protective against corrosion.
What help bacteria survive harsh conditions?
Bacteria can survive harsh conditions by forming protective spores, altering their metabolism to slow down or go dormant, and producing protective compounds or enzymes to combat stressors like extreme temperatures or lack of nutrients. Additionally, some bacteria can form biofilms to create a communal protective shield against external threats.
How thick are the walls of the capillaries that surround the lungs?
It is one to two cell thick
What is a thick protective coat that surrounds the DNA and protein?
The thick protective coat that surrounds DNA and protein is typically referred to as a nuclear envelope or nuclear membrane in eukaryotic cells. This double lipid bilayer structure separates the contents of the nucleus from the cytoplasm, providing a barrier that protects genetic material. Additionally, in some contexts, particularly in viruses, a protein coat called a capsid may surround the DNA or RNA, serving a similar protective function.
What is the protective structure of the carabao?
the protective structure of the Carabao is its thick skin
Bacteria are generally how thick?
Bacteria are typically between 0.2 to 2 micrometers thick.
Is the cell wall of gram positive bacteria thick or thin?
The cell wall of gram positive bacteria is thick.

A diploid zygote with a thick protective wall?
A diploid zygote with a thick protective wall suggests the zygote has undergone fertilization and is preparing for development. The thick protective wall, likely the zygote's outer layer, could provide physical protection and support as the embryo develops. This protective wall may function in maintaining internal conditions suitable for growth and development.
What is the difference between r and s bacteria?
R bacteria have a rough appearance due to the presence of a sugar capsule on their outer surface, making them resistant to the immune system. S bacteria are smooth in appearance and lack the protective capsule, making them vulnerable to the immune system. This difference in structure affects the virulence and pathogenicity of the bacteria.
Which structure helps protect bacteria from a hypotonic environment?
Bacteria can protect themselves from a hypotonic environment by having a thick peptidoglycan cell wall. This wall helps prevent the cell from bursting due to the influx of water. Additionally, some bacteria have a protective outer membrane that provides extra stability in hypotonic conditions.
