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...

Microbiology Lab Midterm Questions and Answers Already Passed Compound microscope 1. Ocular-eyepiece lens (usually 10x) 2. Objective-nosepiece lenses (commonly 4x, 10x, 45x, and 100x) At what magnification do you use the oil immersion technique? 100x. Total Magnification = Magnification (Objective) x Magnification (Ocular) Important Parts of the Microscope Framework, Stage, and Lens System Framework Arm and base are the structural parts of the microscope which support the basic frame.

Last Universal Common Ancestor (LUCA) CORRECT ANSWER Was a microbe of unknown type that lived about 4 billion years ago; the origin of all organisms. What is 16s small unit rRNA used for? CORRECT ANSWER It's used to study construct phylogenetic trees of organisms because it's highly conserved and hasn't changed much over time.

Electron beams can not be used to resolve images of objects. T/F? Correct Answer-False In all types of electron microscopy, electrons pass through the specimen. Correct Answer-False This type of light microscopy can be used to view very thin cells or flagella. It does that by using this property of light. Correct Answer-Dark field; Light scattering In this type of microscopy, light is delayed by passing through the sample and so objects look as if they are out of phase. It employs this ...
