This is a Gram Stain. If the technique was proper, the red rods are Gram-negative and the purple cocci are Gram-positive. This staining technique is used to help identify various bacteria. The Gram-positive bacteria that are purple hold the stain due to it's layered cell membrane. It contains a peptidoglycan layer that acts as a lattice trapping the crystal violet-Iodine dye complex.
What else can I help you with?
Why are contrasting colors important in gram staining?
# Suppose you performed a gram stain on a sample from a pure culture of bacteria and observed a friend of red and purple cocci. Adjacent were not always the same color. What do you conclude? # ## The bacteria was not a pure culture.
What type of organisms are usually observed with light microscope?
Organisms such as bacteria, yeast, algae, fungi, and small protozoa are typically observed with a light microscope due to their size and transparency. These organisms can be magnified to see their cellular structures and characteristics.
Scientists have observed evolution on a rapid time scale in what organism?
Scientists have observed rapid evolution in organisms like bacteria, particularly in response to environmental changes or human intervention such as antibiotics. These fast-evolving bacteria can develop resistance to drugs in a short period of time, highlighting the adaptability and evolutionary capabilities of these microorganisms.
Who invent the bacteria first?
Bacteria is not an invention. Bacteria are microscopic organisms. They were first discovered by Dutch Scientist Antonie van Leeuwenhoek in 1676.
Who Was responsible for the experiment with mice and bacteria that led to the hypothesis that when two bacteria were mixed together something was passed to the living cells?
This experiment was conducted by Frederick Griffith in 1928. He observed that when he mixed a harmless strain of bacteria with a heat-killed virulent strain, the harmless bacteria were transformed into a virulent form. This led to the hypothesis that something in the heat-killed bacteria had transformed the live bacteria.
What would you conclude if you viewed a specimen under a microscope and observed rods and cocci?
I would conclude that there was a mixed culture or that there was a mixed infection. It really would depend on where this came from: a Petri dish or a wound or surface of some sort. Beyond that, I could not say what the species of microbe these are without further testing.
What can the researcher conclude about the bacteria that grow on the nutrient medium?
The researcher can conclude the type of bacteria present based on the appearance of colonies and any biochemical tests performed. They can infer the growth requirements and potential pathogenicity of the bacteria from the growth patterns observed. Further analysis such as DNA sequencing may be needed for accurate identification.

What are some of the speciments that antonvon leeuwenhoek first observed?
Well Anton Van Leeuwenhoek first observed was bacteria.
Who is the founder of bacteria and when was it?
Bacteria were discovered by Antonie van Leeuwenhoek, a Dutch scientist, in the 17th century. He observed microorganisms through a simple microscope he had created, leading to the first documentation of bacteria in 1676.
Scientists have observed evolution in a rapid time scale in what organism?
Bacteria
Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
Why will red and purple cocci be observed from a pure culture of bacteria?
No your Mom will dummy. Oh my i cant belive you calling your mom bacteria. werriod
What conclude mean?
The verb to conclude has two separate meanings : to end, or to make a logical assumption. A concluding act (conclusion) is the final step in a series of activities. Individuals may be concluding that a given situation exists based on the observed evidence.
