What colors gram positive and gram negative bacteria?
Gram-positive cells are purple and the Gram-negative cells are red.
What color is a gram positive cell and what color is a gram negative cell?
In a Gram stain procedure, gram-positive cells appear purple due to their thick peptidoglycan layer, which retains the crystal violet stain. In contrast, gram-negative cells appear pink or red, as their thinner peptidoglycan layer does not retain the crystal violet and is counterstained with safranin. This difference in color is key to differentiating between the two types of bacteria.
Which organ do stem cells start differentiating to from a few weeks after conception?
A few weeks after conception, stem cells begin differentiating into various organs, with the formation of the heart being one of the earliest developments. Around the third week of gestation, the embryonic cells start to organize into structures that will eventually form the heart, along with other critical systems. This process marks the beginning of organogenesis, where stem cells give rise to different tissues and organs.
What are the cells that stay young not elongating not differentiating?
Stem cells are the cells that stay young by not elongating or differentiating. These cells have the ability to self-renew and differentiate into various cell types, allowing for tissue regeneration and repair throughout an organism's lifespan.
What are antigen differentiating cells?
they differentiate the body's own cell to enemy

Why is timing so critical when decolourizing in Gram staining?
Timing is critical when decolorizing in Gram staining because if the decolorizer is left on for too long, it can wash away the crystal violet stain from Gram-positive cells, leading to a false negative result. Conversely, if the decolorizer is not left on long enough, the crystal violet stain may not be fully removed from Gram-negative cells, leading to a false positive result. Timing ensures accurate differentiation between Gram-positive and Gram-negative bacteria.
Are myocardial cells negative or positive in their resting state?
negative at a resting value of -70mV
Are eukayotic cells from you gumline gram-positive or gram-negative?
Eukaryotic cells, such as those found in the gumline, do not fall under the categories of gram-positive or gram-negative bacteria. The gram staining technique is used to determine the cell wall structure of bacteria, not eukaryotic cells. Eukaryotic cells have a different cellular structure, including a nucleus and membrane-bound organelles.
Why will gram positive cells stain gram negative?
Contamination
What are cheek cells gram positive or gram negative?
Cheek cells do not have a cell wall, therefore they are neither gram positive nor gram negative. Gram staining is a technique used to differentiate bacteria based on the composition of their cell wall, which animal cells like cheek cells do not possess.
Can your blood type change from positive to negative?
No, your blood type cannot change from positive to negative. Blood type is determined by the presence or absence of certain antigens on red blood cells, not by the positive or negative Rh factor.
Construct a Venn diagram to illustrate the similarities and differences between gram positive gram negative cells?
Not really possible to make a venn diagram, but here's a list: Similarities: In Bacteria Involve a peptidoglycan layer Differences Gram-negative is much more toxic Gram-negative is crystal violet in the Gram stain while Gram-positive is red

Positive and Negative affect of gamna rasdation?
The negative affects are nausea, vomiting and hair loss. The positive affects such as chemo therapy, which decreases or stops the cancer cells.
