- True or false ? images will appear brighter when light waves are in phase. the condenser portion of the microacope focuses light on the speciment.True or false? each objective of a phase contrast microscope contains a phase plate. most cultured mammalian cells grow best at 37C. the oculars on the compound light microscope are typically 10X.Good day! Could you help me answer the question: What are the primary limitations imposed by using Hanging-drop method (or Wet mount) to observe microorganisms? State at least two (2) accounts with explanation. Thank you!
- It is a couple of years in the future and you have taken a job as a WSU lab prep assistant. You are cleaning up after a group of MICR 2054 students. They have been using Bacillus subtilis, a species that produces endospores. Which of the following techniques would you use to clean their glassware? Group of answer choices Boiling Pasteurization Autoclaving Any of the listed methods. Pasteurization, autoclaving, and boiling are all equally effective against endosporessubject - microbiology need help with these two problems asap! due tomorrow by 6 am!TRUE or FALSE only! 1. We need to look at the body tube’s side when focusing to prevent the breakage of the microscope glass slide. 2. In transferring samples of bacteria from one medium to another growth medium a sterilized inoculating loop is used. 3. In drying leaf samples for a thesis experiment, the proper laboratory instrument to be used is the autoclave.
- Help Answering Why is it important for all plankton monitors to use the sample protocol for both sample collection and identification? What are the ways you can control the amount of light passing through your specimen? What is resolution and how is it improved? With which objective is it permissible to use the course adjustment knob? Many of the plankton images were taken using the 40x objective on a compound microscope. What is the total magnification?What statement correctly explains why moist-heat is more effective than dry-heat for sterilization purposes? The microbe's molecules are resistant to alteration in the absence of water. Dry heat will always be a lower temperature than moist heat. Dry heat dehydrates the microbes, and dehydration is a method of preserving microbes. Water is a good conductor of heat.Which of the ff. describes the components of a turbidimeter in the correct order? a.) light source --> sample holder --> photon detectorb.) light source --> sample holder --> wavelength detector --> photon detectorc.) light source --> wavelength selector --> sample holder --> photon detectord.) light source --> wavelength selector --> sample holder --> wavelength detector --> photon detector
