Discuss how the findings of Louis Pasteur may have inspired Joseph Lister’s development of aseptic techniques in surgical settings. Be sure to mention the following in context of Lister’s findings: Spontaneous Generation and Germ Theory. In addition discuss how the understanding of germ theory has been applied in the development of medical microbiology. (Section 1.6 in the textbook)
Discuss the term ubiquitous, evaluating why it is an appropriate term to use to describe microbes and their importance (Section 1.2 in textbook). Include the following in your response and provide examples:
the importance of microorganisms in shaping the environment (Section 1.2 in the textbook)
their use in biotechnology (Section 1.3 in the textbook).
You are a scientist researching West Nile virus, a mosquito-borne pathogen. You note that a number of cases of West Nile disease in your county skyrocketed to their highest levels ever this past summer, which also was the wettest summer in 100 years. Using the scientific method develop a sound hypothesis explaining the increase in disease cases last summer and design a method for testing this hypothesis. (Section 1.6 in the textbook)
Draw a phylogenetic tree that shows the evolutionary relationships between the domains bacteria, archaeans, and eukaryotes. You only need to include the three domain names in your diagram. Then answer the following question: What molecular evidence supports your drawing? Then discuss how molecular evidence is advantageous over relying on structural similarities to accurately classify species Provide specific details to support your answer. Be sure to read Section 1.7 in the textbook over the Universal Tree of Life. Videos have been provided below demonstrating how to add a drawing to a Word document and a Google Doc.
Differentiate the following chemical bonds: ionic, polar covalent, nonpolar covalent, and hydrogen. Be sure to mention the following where appropriate: anion, cation, and electronegativity of covalent molecules. (Section 2.1 in the textbook)
