Compare gram-positive bacteria with gram-negative bacteria?
Gram-positive bacteria have a thick layer of peptidoglycan in their cell wall that retains the crystal violet stain during Gram staining, making them appear purple. In contrast, gram-negative bacteria have a thinner layer of peptidoglycan and an outer membrane that can be disrupted during the staining process, causing them to appear pink. Gram-negative bacteria are generally more resistant to antibiotics due to the presence of this outer membrane.
What is the outer layer of a gas terrestrial planet?
The outer layer is atmosphere.
How does the cell wall aid in classifying bacteria?
The presence or absence of a cell wall is a key characteristic used in classifying bacteria. Bacteria are classified into two major groups based on their cell wall structure: Gram-positive bacteria have a thick peptidoglycan layer in their cell wall, while Gram-negative bacteria have a thinner peptidoglycan layer surrounded by an outer membrane. This classification helps scientists differentiate between different types of bacteria.
Which stratum is the tough outer layer of the skin?
The stratum corneum is the tough outer layer of the skin.
What is the difference between gram plus and?
Gram positive bacteria stain purple with the Gram stain. This is because of the fact that they contain a thick layer of murein in their cell wall, which takes up the stain very well. Gram negative bacteria, however, do not display the thick layer of peptidoglycan on their outer surface. Therefore, they stain red with the counter stain.
What is the sticky layer of germs on teeth called?
A sticky layer over the teeth called dental plaque. It growth cause is the formation of germs(bacteria) in our mouth on teeth every day and use sugars from foods and drinks we take. It attacks the tooth's outer layers (enamel and dentine) and eats them away.
What are the key differences between gram-negative and gram-positive bacteria?
Gram-negative bacteria have a thin peptidoglycan layer in their cell wall and an outer membrane, while gram-positive bacteria have a thick peptidoglycan layer but lack an outer membrane. Gram-negative bacteria also have lipopolysaccharides in their outer membrane, which gram-positive bacteria do not have. Additionally, gram-negative bacteria are typically more resistant to antibiotics due to the presence of the outer membrane.
What layer is beneath the outer membrane?
The layer beneath the outer membrane is called the periplasmic space or the periplasm. It is a gel-like region that contains proteins and other molecules, and it separates the outer membrane from the inner membrane in Gram-negative bacteria.
What is the stratum?
It is the deepest of the five layers of the skin layer epidermis, which is our outer skin. It is where the skin cells are produced, and can be called the stratum basale germination layer
What is the outer layer tooth?
The outer layer of the tooth is enamel.

What structure produces?
Aldosterone is produced in the adrenal cortex= the outer layer of the adrenal gland. The adrenal glands are on the top of the kidneys.
What is the outer layer of a gas terrestrial planet?
The outer layer is atmosphere.
What is the difference between g plus ve and g-ve bacteria?
Primarily, the difference lies in their cell walls. G+ve bacteria have a thick peptidoglycan layer whereas G-ve bacteria have an outer membrane of lipopolysaccharides and proteins, a periplasmic space, and only a thin layer peptidoglycan.
What layer of skin is beneath the outer layer?
The epidermis is the outer layer of skin. The dermis is beneath the epidermis.
What layer of skin is the outer layer of skin?
The epidermis is the outer layer of skin. The dermis is beneath the epidermis.
What is the suns outer most layer?
The outer layer of the sun is called the corona.
