What else can I help you with?
What characteristic probably was used in naming cyanobacteria?
the slime layer
What part of a microscope should you adjust to observe the lower layer of a sample?
To observe the lower layer of a sample using a microscope, you should adjust the focus by turning the fine adjustment knob slowly to bring the lower layer into view. This will help bring the sample into sharper focus so you can see details on the lower layer more clearly.
Are cyanobacteria classified as gram-negative bacteria?
Yes, cyanobacteria are classified as gram-negative bacteria. This classification is based on the structure of their cell walls, which contain a thin layer of peptidoglycan surrounded by an outer membrane. When stained using the Gram staining technique, cyanobacteria appear pink or red under a microscope, indicating that they do not retain the crystal violet stain and are therefore gram-negative.
What was responsible for the accumulation of limestone deposits known as stromatolites?
Stromatolites are formed by the growth of layer upon layer of cyanobacteria (formerly known as blue-green algae) on shallow marine or freshwater environments. The cyanobacteria trap and bind sediments, leading to the formation of limestone deposits over time.
What is the layer immediately beneath the plasma in a sample of centrifuged blood?
Mononuclear cells
Sample of good slogan on ozone layer?
There could be many slogans for ozone layer. Ozone protection, Life protection is one of them.
How can you find the the age of the charcoal layer?
The age of a charcoal layer can be determined using radiocarbon dating, a technique that measures the decay of the carbon-14 isotope in the charcoal sample. By comparing the ratio of carbon-14 to carbon-12 in the sample to that of the atmosphere, scientists can estimate the age of the charcoal layer.
Why is nujol used?
to provide a protective layer or coating for the sample if the sample is a reactive sample. forming a protective layer or coating would prevent decomposition of the sample during the IR reading process.
What is a clevenger apparatus?
Clevenger apparatus is used to determine the volatile oil content in a given sample. The oil layer settles on top of the aqueous layer.
The rock samples collected from the bottom of the drill hole came from which earth layer?
The rock samples collected from the bottom of the drill hole likely came from the Earth's crust or upper mantle layer, as drill holes typically do not penetrate beyond the uppermost layers of the Earth's lithosphere. To determine the exact layer, further analysis of the composition and characteristics of the rock samples would be necessary.
Which type of microscope requires a nonmetal sample to be prepared for viewing by coating it with a thin layer of a conductive material?
A scanning electron microscope (SEM) requires a nonmetal sample to be coated with a thin layer of a conductive material, such as gold or carbon, to prevent charging of the sample and improve image quality. This coating allows for better conductivity of electrons, resulting in clearer imaging and more accurate analysis of the sample's surface.
What is responsible for the accumulation of limestone deposits known as stromatolites?
Sediment trapping and the growth and metabolic activities of matlike cyanobacteria colonies contribute to the creation of stromatolites. Small particles of calcium carbonate settle onto the sticky matlike colonies of cyanobacteria forming thin layers of calcium carbonate. The cyanobacteria then build up over the calcium carbonate layer (so as not to be buried and killed) producing another sticky surface where more fine particles of calcium carbonate can be trapped.
