Phase contrast microscopy Study guides, Revision notes & Summaries

Model organisms are often used to study fundamental biological processes that can be applied to other organisms, such as humans. The bacteria E. coli is a popular model organism because it divides rapidly and can be genetically manipulated, among other reasons. Given what you know about the differences between prokaryotic cells and eukaryotic cells, which of the following biological processes is the most suitable for study using E. coli as the model organism. DNA replication DNA replication is...

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...
