The condensor of microscope is used to control the light intensity so it first depends on the viewer and secondly it should be so adjusted so that the light intesity does not shoots high as it can damage the specimen and is also harmfull to the eyes and even to the microscope. It is also to be see that the specimen view clearly against its background.

In what ways do bacteria and archaea differ from each other?
Bacteria and archaea are both types of single-celled microorganisms, but they differ in their cell wall composition, genetic makeup, and metabolic processes. Bacteria have a cell wall made of peptidoglycan, while archaea have a different type of cell wall. Archaea also have unique genetic sequences and metabolic pathways that set them apart from bacteria.
What are the characteristics of domain bacteria?
The characteristics of domain bacteria is that it is a prokaryote , bacteria can be found in soil , water , and even on and inside the human body . some bacteria causes diseases , such as pneumonia . Other bacteria make chemicals that help humans fight disease-causing bacteria . - by yha gurl v.rizzle !Unicellula
What is the difference between bacteria and archaea in terms of their genetic makeup and evolutionary history?
Bacteria and archaea are both types of single-celled microorganisms, but they differ in their genetic makeup and evolutionary history. Archaea have unique genetic characteristics that set them apart from bacteria, such as different cell membrane structures and genetic sequences. In terms of evolutionary history, archaea are believed to be more closely related to eukaryotes (organisms with complex cells) than to bacteria. This suggests that archaea and bacteria evolved separately and have distinct evolutionary paths.
How do you culture bacteria for scientific research and experimentation?
To culture bacteria for scientific research and experimentation, a sterile nutrient-rich agar medium is used to provide the necessary nutrients for bacterial growth. The bacteria are then inoculated onto the agar surface using a sterile technique, such as streaking or spreading. The agar plates are then incubated at a specific temperature for a set period of time to allow the bacteria to grow and form visible colonies. These colonies can then be isolated and studied for various research purposes.
What are the parts of a microscope and what do they do?
Eyepiece Lens: the lens at the top that you look through. They are usually 10X or 15X power.Tube: Connects the eyepiece to the objective lensesArm: Supports the tube and connects it to the baseBase: The bottom of the microscope, used for supportIlluminator: A steady light source (110 volts) used in place of a mirror. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.Stage: The flat platform where you place your slides. Stage clips hold the slides in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs. One moves it left and right, the other moves it up and down.Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X. To have good resolution at 1000X, you will need a relatively sophisticated microscope with an Abbe condenser. The shortest lens is the lowest power, the longest one is the lens with the greatest power. Lenses are color coded and if built to DIN standards are interchangeable between microscopes. The high power objective lenses are retractable (i.e. 40XR). This means that if they hit a slide, the end of the lens will push in (spring loaded) thereby protecting the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses.Rack Stop: This is an adjustment that determines how close the objective lens can get to the slide. It is set at the factory and keeps students from cranking the high power objective lens down into the slide and breaking things. You would only need to adjust this if you were using very thin slides and you weren't able to focus on the specimen at high power. (Tip: If you are using thin slides and can't focus, rather than adjust the rack stop, place a clear glass slide under the original slide to raise it a bit higher)Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400X and above). Microscopes with in stage condenser lenses render a sharper image than those with no lens (at 400X). If your microscope has a maximum power of 400X, you will get the maximum benefit by using a condenser lenses rated at 0.65 NA or greater. 0.65 NA condenser lenses may be mounted in the stage and work quite well. A big advantage to a stage mounted lens is that there is one less focusing item to deal with. If you go to 1000X then you should have a focusable condenser lens with an N.A. of 1.25 or greater. Most 1000X microscopes use 1.25 Abbe condenser lens systems. The Abbe condenser lens can be moved up and down. It is set very close to the slide at 1000X and moved further away at the lower powers.Diaphragm or Iris: Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. There is no set rule regarding which setting to use for a particular power. Rather, the setting is a function of the transparency of the specimen, the degree of contrast you desire and the particular objective lens in use
What should the brightness level of my monitor be set to for optimal viewing experience?
For optimal viewing experience, the brightness level of your monitor should be set to around 120 cd/m. This level is recommended to reduce eye strain and provide a comfortable viewing experience.
How should the condenser be set up for optimal performance in this experiment?
To achieve optimal performance in the experiment, the condenser should be set up with proper alignment and a sufficient cooling water flow rate. Ensure that the condenser is clean and free of any blockages to maximize heat transfer efficiency. Additionally, adjust the condenser height to maintain a steady flow of the distillate and prevent any vapor leaks.
Where should an adjustable condenser be set for maximum resolution?
An adjustable condenser in a microscope should be set at the highest position for maximum resolution. This position allows for maximum illumination and better focus of the specimen, resulting in sharper and more detailed images.
How to test the pionts and condenser on a Ford truck?
Testing the condenser. (capacitor) Open the points and set the meter on ohms.
What problems can a bad ignition condenser cause on a 1971 volkswagen super beetle?
If you have a bad condenser your car won't run. Always carry a spare set of points and condenser (you change them together) in the glovebox.
What should be done before viewing through a compound microscope?
you should make sure the microscope is clean and ready. and that it is set on the right setting. i actually have no clue . suckerrr
How do you remove a set on polyvore?
when you are viewing the set, click on delete set. it is underneath "edit this set" and "___ people like this set"
Which set should be used to observe the ovules of a flower?
The type of viewing determines the set to be used for observing the ovules of a flower. Angiosperms have protected ovules that may be observed through dissection, fluorescence and microscopy. Gymosperms, especially ginkgos, offer easy viewing because of their unprotected ovules.
What is the arrangement of the telescope for optimal viewing conditions?
For optimal viewing conditions, the telescope should be set up in a location with minimal light pollution and a clear line of sight to the object being observed. The telescope should be properly aligned and focused, with the eyepiece positioned at the correct distance for the user's eyes. Additionally, the telescope should be stable and not affected by vibrations or wind, and the user should be comfortable and positioned in a way that allows for steady viewing.
88 Honda trx 350 has no spark coil is good what else could it be?
An 88 Honda trx 350 should have a set of points and a condenser under a side cover on the engine. If the points do not work properly of the condenser is bad then there will be no power going into the coil and there wont be a spark.
How do you charge the condenser for a non HEI ignition on a 1970 Chevy 350?
If you're asking how to change the condenser, it is under the rotor. Remove cap and rotor, remove condenser wire from contact set (either held in place with a screw or spring tension), remove the screw that holds the condenser bracket ( magnet or screw starter is very helpful), then reverse procedure to install new condenser.
What is the difference between a partial condenser and a total condenser?
In a total condenser te temperature is lowerd to a level on which all gasses turn to liquids. with a partial condenser you can separate gasses on there dew point. It means that the temperature is set to a level on wich a one or several gasses leave the partial condenser as a liquid and the others as a gas.
