Biology 1406 Lab Exam 1 Questions and Answers Already Passed Why is oil immersion used? To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? Illuminator-The light source for the microscope.Diaphragm-Controls the amount of light entering the condenser. Co...

BIOD 171 Portage Learning Exam 3 Define the measurements micrometer and nanometer. - ANSWER-A micrometer is one-millionth of a meter and a nanometer is one-billionth of a meter. What are the two critical factors that influence your ability to see an object? - ANSWER-The resolution and the contrast. Resolution is the distance between two objects where you can still see them as separate. Contrast is the difference in light between two objects. If you wish to increase the amount of light goin..

BIOD 171 MODULE 3 EXAM Questions and Answers with Complete Solutions rated A+ Immunochemistry - involves staining of cells to see structures microscopy - the use of light or electrons to magnify objects Micrometer (um) - 10^-6 m, measures size of cells Nanometer (nm) - 10^-9m, used to measure cellular organelles and viruses Magnification - the ratio of an object's image size to its real size Resolution of a microscope - ability to distinguish two objects as separate entities Contrast Mi...

.Define the measurements micrometer and nanometer Your Answer: A micrometer is the measurement of one millionth of a meter. A nanometer is one-billionth of a mete

micrometer one millionth of a meter, 10^ -6 2. nanometer one billionth of a meter, 10^-9 3. Resolution the distance between two objects at which the objects still can be seen as separate 4. What happens if the resolution is poor? Poor or low resolution means two (or more) objects may appear as one. 5. Contrast the difference in light absorbance between two objects. 6. What happens if there is poor contrast? gives a high background and makes the visualization of multiple objects diff...

A nanometer is defined as: - 10-9 A nanometer is defined as one-billionth of a meter True or False: A nanometeris longer than a micrometer - False. A nanometer is 1,000 times smaller than a micrometer. Resolution and contrast are two critical factors that influence your ability to see an object. Explain each. - Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor or low resolution means two (or more) objects may appear as one. *Cont...
