    Two different techniques for quantifying species diversity within a community are being compared in order to determine which technique yields the most consistent values. Higher consistency is indicated by lower variation among replicate estimates. Each technique involves employing a particular sampling protocol in the field and then using the results to calculate an index of diversity. Each sampling protocol is repeated six times on the same community, yielding six estimates of the species diversity of that community. The two indexes...

    5. Why are simple stains able to "stick” to bacteria? Explain the chemical properties of the stain and bacteria surface. 3-Preparation of Bacterial Smears and Simple Stains Introduction Microbial cultures are handled using aseptic technique. Aseptie technique is a set of procedures used to minimize contamination of materials by microorganisms from the environment, and to minimize the spread of cultures around the laboratory. In this experiment, you will be using an inoculating loop to transfer bacteria from a culture tube...
