What else can I help you with?
Can live specimens be used in a TEM microscope?
Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.
Contrast a prepared slide and a wet-mount slide?
A prepared slide is sealed by acrylic or any other medium. After the solvent evaporates, the specimen is locked under the slip. On the other hand, a wet mount slide has the specimen prepared just before it is put under microscope.
Which laboratory tool is used for growing live specimens?
An incubator is typically used for growing live specimens in a laboratory setting. It provides a controlled environment in terms of temperature, humidity, and lighting to support the growth and development of the specimens.
What microscope would you use to observe a living amoeba?
A compound light microscope would be the most suitable choice for observing a living amoeba. This type of microscope allows for observation of live specimens under magnification, while also providing enough clarity to study cellular structures.
What laboratory tool is used for growing or reproducing live specimens?
An incubator is commonly used in laboratories for growing or reproducing live specimens. It provides controlled conditions such as temperature, humidity, and lighting to support the growth of various organisms.
What are the advantages of studying live specimens?
There are many advantages of studying live specimens including being able to observe patterns. These patterns can be eating and hunting patterns or sleeping patterns for example.
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
What is the purpose of a wet mouth slide?
A wet mount slide is used in microscopy to observe live specimens, such as microorganisms, cells, and tissues, in a liquid medium. The purpose is to keep the sample hydrated and allow for the examination of motility and natural behavior without the distortion that can occur from dry slides. It also helps in enhancing contrast and clarity of the specimen, making it easier to identify and analyze various cellular structures.
When was Slide on Live created?
Slide on Live was created on 1993-09-28.
How do wet mount slides differ from prepared slides?
Wet mount slides are temporary preparations that involve placing a specimen in a drop of liquid, usually water, and covering it with a coverslip, allowing for observation of living organisms or dynamic processes. In contrast, prepared slides are permanent mounts where specimens are treated, stained, and sealed between a slide and coverslip, providing a stable and often more detailed view of the specimen's structure. Wet mounts are typically used for observing live specimens, while prepared slides are ideal for detailed anatomical studies.
On Howrse what are temporary employees?
Temporary employees are employees that are not live players.
What are some advantages of light microscopes and electron microscopes?
Light microscopes are advantageous due to their simplicity, ease of use, and ability to observe living specimens in natural colors, making them ideal for studying biological processes. They typically allow for quick imaging and are less expensive than electron microscopes. In contrast, electron microscopes provide much higher resolution and magnification, enabling the visualization of fine cellular structures and details at the nanoscale. However, they require more complex sample preparation and cannot observe live specimens.
What laboratory tool used in growing live specimens?
Commonly a petri dish, although there are many other mediums...even chicken broth!
Can live specimens be used in a TEM microscope?
Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.
How do you examine live bacteria microscopically?
To examine live bacteria microscopically, a drop of the bacterial culture is placed on a microscope slide and covered with a coverslip. The slide is then observed under a light microscope at high magnification to see the bacteria in their natural, living state. Additional techniques like phase contrast or dark-field microscopy can also be used to enhance the visibility of the bacteria.
Contrast a prepared slide and a wet-mount slide?
A prepared slide is sealed by acrylic or any other medium. After the solvent evaporates, the specimen is locked under the slip. On the other hand, a wet mount slide has the specimen prepared just before it is put under microscope.
Are Antarctica's inhabitants permanent or temporary?
Humans who work and live on the continent, and animals that breed there, are all temporary.
