<p> (24)Before you arrive for the Survey of Prokaryotes lab, please</p><p>1. Read the lab thoroughly, noting all safety guidelines. </p><p>2. Answer these preparatory questions:</p><p>What safety procedures should you be sure to follow during this lab period?</p><p>______</p><p>______</p><p>______</p><p>What sort of evidence led to the reorganization of the taxonomy of prokaryotes in 1996?</p><p>______</p><p>Describe the general nature of the habitats of organisms in domain Archaea.</p><p>______</p><p>What is the other domain of prokaryotes?______</p><p>When a taxonomic scheme is established for a species or for groups of species, is it permanent? If not, what can change established taxonomy?</p><p>______</p><p>______</p><p>If you are examining an unknown cell through the microscope, list three ways that distinguish it as a prokaryote and not a eukaryote.</p><p>______</p><p>How would Bacillus anthracis appear different from Spirillum volutans? Do all bacterial names reflect the appearance of the bacteria as these do?</p><p>______</p><p>______How is binary fission different than mitosis?</p><p>______</p><p>______</p><p>______</p><p>______</p><p>How might conjugation benefit bacterial survival?</p><p>______</p><p>______</p><p>______</p><p>Gram negative bacteria are generally more resistant to antibiotics than Gram positive bacteria. Using Figure 24.6 as a guide, what structure in Gram negative bacteria (but not Gram positive bacteria) supports this idea? ______</p><p>How does oil help in the visualization of structure through the microscope?</p><p>______</p><p>Can you ever see bacteria with the naked eye? Explain your answer.</p><p>______</p><p>How do bacteria make nitrogen available to living things?</p><p>______Below is a diagram of 4 different antibiotics (numbered 1-4 and shown as a in the diagram) that are being tested in a petri dish that has been inoculated with bacteria. After a sufficient incubation period, bacterial growth occurred over the plate in all areas except in the zones of inhibition (shown with in the diagram) around the antibiotics. Would you choose antibiotic 1, 2, 3, or 4 to limit the growth of this bacterium?______</p><p>1 antib 4 2 3</p><p>From the results shown here, would it be reasonable to conclude that the most effective antibiotic in this example would be an effective antibiotic against any bacterium? Why or why not?</p><p>______</p><p>Do cyanobacteria have chloroplasts?______</p><p>You are presented with an unknown cell, and are charged with the duty of its identification. As you study the cell, you note that it lacks a nucleus, it has unusual cell walls, and that is rRNA is distinctly different. To which domain would you assign it?</p><p>______</p><p>List five human disease that are caused by bacteria. Include the name of the disease and the name of the bacteria that cause the disease.</p><p>Human Disease Bacterial cause of the disease Is boiling water an effective way to kill all bacteria? Explain your answer.</p><p>______</p><p>______</p><p>______</p><p>Write an equation for nitrogen fixation that shows the reagents, enzyme, and product.</p><p>______</p>
