- Which of the following is not a classification of bacteria? Bacillus Spirilla Barilla CocciWhat is a lawn of bacteria? an uneven layer of bacteria covering an entire surface an uneven layer of bacteria covering only part of a surface a uniform, even layer of bacteria covering an entire surface a uniform, even layer of bacteria covering part of a surfaceWhich of the following classification methods relies on the morphology of organisms? analysis of nucleic acids physical characteristics phage typing biochemical tests serological tests
- Which species concept would most likely be used to describe microbial species diversity? It is not: Morphological Typological Biological Why is it? Operational Taxonomic Unit (OTU)Which statement about the cellular arrangments of bacteria is NOT correct? Spiral bacteria are typically single. A diplobacillus arrangement consists of two cocci adhering to one another. A chain of bacilli is called a streptobacillus arrangement. A cube-shaped arrangement of cocci is a sarcina. A square-shaped arrangement of cocci is a tetrad.The process of collecting characteristics of your unknown bacterium can be helped by the use of a dichotomous key. A dichotomous key is a flowchart that can be used to identify an organism. a) in your own words explain how to create and use a dichotomous key to identify unknown bacteria
- Which genera have members that undergo conjugation in order to acquire genetic variability? Trichomonas Giardia Entamoeba Trypanosoma ParameciumThe generation time of a bacterial culture that produces two generations per hour is: a. Equal to that produces three generations per hour bLesser than that produces five generations per hour than that produces three generations per hour Lesser than that produces four generations per hour Greater than that produces three generations per hourFill in the Blank. Round it to the nearest whole number. A mutation occurs in a single bacterium that causes it to produce a new enzyme. This enzyme helps the bacterium process nutrients more efficiently, increasing the bacterium's odds of survival. Every 30 minutes, the bacteria in the colony divide, passing their genes on to their offspring. Some bacteria survive, while others do not. Because resources are limited, the colony has a steady population of 114 bacteria. The bacterial colony is shown below at three different time intervals. The picture would be here: Assume that the survival trend shown in the diagram continues. At 3.0 hours, the mutant bacteria will make up _____ percent of the entire colony.
