Portage Learning: Microbiology Module 3 Already Graded A Define the measurements micrometer and nanometer. A micrometer (μm) is defined as being one-millionth of a meter and is commonly designated at 10-6 meters. A nanometer (nm) equals 10-9 m or one-billionth of a meter. What are the two critical factors that influence your ability to see an object? Resolution and contrast. Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor or low r...

MICP MICROSCOPY PRACTICAL EXAM QUESTIONS & ANSWERS 2024/2025 A microscope that uses multiple lenses to magnify the image of a sample. is used to examine materials at high magnification (40-1000x), which is accomplished by combining the effects of two lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample). The total magnification is derived by multiplying the ocular lens magnification by the objective lens magnification. - ANSWERSCOMPOUND MICROSCOPE To...

Malaria correct answers Plasmodium is famous for causing which disease? Field of View correct answers the diameter of the circle of light that you see when looking into a microscope 40x correct answers total magnification used on the shortest objective 100x correct answers total magnification used on low power objective 400x correct answers total magnification used on high power objective Voltage Control Dial correct answers What part of the microscope should increase the light in...

If the total magnification of a microscope can be increased by simply adding more lenses, why are bright-field light microscopes not outfitted to magnify things greater than 1300×? correct answers Because the resolution limit for a light microscope is about 0.2μm, magnifications above this will not produce clear images. Fluorescent microscopy differs from other types of light microscopy in that it requires correct answers the use of an ultraviolet light source. Why is it important to cen...
