What are the key differences between gram-negative and gram-positive bacteria in terms of their cell wall structure and response to Gram staining?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell wall compared to gram-positive bacteria. They also have an outer membrane containing lipopolysaccharides. When subjected to Gram staining, gram-negative bacteria appear pink or red, while gram-positive bacteria appear purple or blue.

The major criteria used in placing bacteria into different groups is based on differences in?
The major criteria used in placing bacteria into different groups is based on differences in their cell wall structure, shape and arrangement, metabolism, and genetic composition. These characteristics help scientists classify bacteria into different taxonomic groups based on their shared traits and evolutionary relationships.
Amoebas and bacteria are grouped into different domains because?
Amoebas belong to the domain Eukarya, which includes organisms with complex cells containing a nucleus, while bacteria belong to the domain Bacteria, which are prokaryotic organisms with simpler cells lacking a nucleus. The distinction between these two groups is based on fundamental differences in cell structure and organization.
What are the 3 groups all living things can be placed into?
The three main groups all living things can be classified into are Archaea, Bacteria, and Eukarya. These groups are based on differences in cellular structure and biochemistry.
What are the characteristics used to classify organisms into the two domains?
The main characteristics used to classify organisms into the two domains, Bacteria and Archaea, include differences in their cell wall composition (peptidoglycan in Bacteria, absence of peptidoglycan in Archaea), membrane lipid structure (fatty acids in Bacteria, branched hydrocarbons in Archaea), and sensitivity to antibiotics (Bacteria are sensitive, Archaea are not).
Can bacteria have RNA within their cellular structure?
Yes, bacteria can have RNA within their cellular structure. RNA is a crucial molecule that plays a key role in protein synthesis and gene expression in all living organisms, including bacteria.
Is b subtilus grampositive?
B. Subtilus is a rod or bacilus shaped, gram positive bacteria
Eliminate gram-positive bacteria from a mixture of gram and gram-bacteria which procedure would be best 1treatment with mild detergent or lysozyme?
to eliminate gram positive bacteria from a mixture of grampositive and gram negative bacteria which procedure would be best first treatment with mild detergent or lysoyme
What is a description of the structure of bacteria?
The structure of a bacteria is your mom
How do the two members of the two domains of prokaryotes differ?
there are important differences in the structure and chemical makeup of their cells.Some prokaryotes are unicellular, and others are multicellular.Although bacteria and archaea are similar in some ways, there are important differences in the structure and chemical makeup of their cells.
Why are antibiotics drugs effective against bacteria without hurting humans because the antibiotics rely upon differences in the structure of human and bacteria?
863-604-3477 have 150 10/650
What are bacteria and archaea most easily distinguished by from each other?
Bacteria and archaea can be most easily distinguished by differences in their cell wall composition. Bacteria have cell walls made of peptidoglycan, while archaea do not contain peptidoglycan in their cell walls. Additionally, they have differences in membrane lipid structure and genetic makeup.
Why do you think bacteria are classified as animals?
Bacteria are not classified as animals. Animals belong to the eukaryota domain, while bacteria belong to their own separate domain, due to numerous differences in cell structure, the ability of animals cells to form tissues, etc.
What are the differences between bacteria and humans?
There are many differences * Bacteria are microscopic while human is not. * Bacteria are prokaryotes. Human is eukaryote. * Bacteria has a cell wall. * Bacteria are the earliest known organisms on earth.
What causes differences in cheese?
bacteria
What stain is used to distinguish differences between the cell walls of medically important bacteria?
Gram stain is commonly used to distinguish differences between the cell walls of medically important bacteria. This technique categorizes bacteria into Gram-positive (purple) and Gram-negative (pink) based on their cell wall structure, aiding in identification and classification of bacteria in microbiology.
What structure is found in bacteria?
Bacteria is classified as being a prokaryotic. This means that bacteria lacks any type of membrane structure which can be found in eukaryotes.
What is structure is not found in bacteria?
Bacteria is classified as being a prokaryotic. This means that bacteria lacks any type of membrane structure which can be found in eukaryotes.
