Module 04 Homework questions.undefinedThis assignment contains four short answer questions. In some cases, there is a supplied list of keywords that should be used in developing your answer. You should use the knowledge gained in the readings and other assignments in this module. These are thought questions meant to help you process information that you have been exposed to in this module and if applicable, in previous modules. You may use outside sources, but you must use citations to show where you obtained the information. This is an untimed assignment. You only have one opportunity to complete this assignment.Question 1(3 points)undefinedYou are interested in obtaining Staphylococcus aureus for a study investigating the prevalence of methicillin-resistant Staphylococcus aureus in the general population. You have received several samples and are ready to start your isolation procedures. Describe the personal protective equipment that would be needed and three different culturing techniques that can be used to obtain organisms to produce pure cultures. State if you use general or selective media and which specific media you would choose. How would you determine if the culture was contaminated? What is the first step you would take if you detected contamination? undefinedQuestion 2 (3 points)undefinedExplain the different stages of syphilis. (Terminology/topics to include: causative organism (morphology, gram-stain reaction), mode of transmission, chancre, gumma, symptoms, likelihood of infection, treatment options at different stages, damage that can occur during different stages, prevention methods).undefinedQuestion 3 (3 Points)undefinedList three protozoan infections of the circulatory system that are transmitted by arthropods. Include the disease name, specific organism (genus species), vector that is the intermediate between hosts, and disease progress in humans.undefinedQuestion 4(3points)undefinedMany types of fruits and vegetables can be fermented into alcoholic beverages. Such was the case recently when prisoners in Utah attempted to make an illegal beverage called “pruno”; however, someone added a weeks-old baked potato to the mix, letting a microbe into the party who was clearly uninvited. Consumers of the pruno began to develop difficulty swallowing, vomiting, double vision, and muscle weakness; three required ventilation therapy. No deaths were attributed to the contaminated beverage.

SCIENTIFIC METHOD ARTICLE-STYLE REPORT Download the report sheet, complete it, and then submit.Do not change the format. All blue shaded areas require answers in 12 pt. font. Write this report as a research article but follow the format below and submit your report to your instructor. Adjust the size of the blue shaded areas as needed. Do not use personal pronouns (I, you, they, etc.) when writing your report. I. Title Title – underline title and describe lab content concisely, adequately, appropriately. II. Abstract Abstract – brief paragraph about Convey a sense of the full report concisely and effectively of what was done. Convey a sense of the full report concisely and effectively of what was found as a class (not your own individual work). III. Introduction Introduction Provide adequate scientific background information on the topic (pinto bean germination). This is information above and beyond what is provided in the unit. You may use books, journals and internet sites. State the aim and hypothesis and provide a logical reasoning for it. State your variables. Be specific and state the independent variable (the variable you manipulate), dependent variable (the variable you measure), and control variables (the variables that need to be constant for the two groups). IV. Materials & Methods Materials and Methods – be specific. Include a list of materials used. Include the complete procedure. Numerate the steps. You may copy the procedure verbatim from the unit. V. Results Results – include Open with effective statement of overall findings. Present visuals that are clear and accurate (table with seed germination class results) Present clear verbal findings and provide support (provide the test conclusion). VI. Discussion Discussion – discuss your results. Open with an effective statement of support/no support for the hypothesis (includes conclusion statement). Provide logic explanations. Back up statements with references to appropriate findings. Sufficiently address other issues pertinent to the lab. VII. Conclusion Conclusion – Describe what has been learned. VIII. References Reference – list sources used. You must include two references in APA style LAB QUESTIONS: I. List the Scientific Method Steps in order (conclusion, experiment, hypothesis, question, observation and results) Steps 1 2 3 4 5 6 II. Experiment (your results only) Environment Number of seeds tested Number of seeds germinated Germination percentage Seeds in water 100 Seeds in H2O2 100 III. Questions: Address the following using class results (not just yours) What is the germination percentage of seeds in water within 72 hours? Calculate this answer based on the results gather from classmates.What is the germination percentage of seeds in H2O2 within 72 hours? Calculate this answer based on the results gather from classmates.Is there a difference in the percentage of seeds germinated between the two groups?What is the test conclusion? The conclusion is either ‘reject the null’ or ‘fail to reject the null.’Is there a significant difference in the percentage of seeds germinated between the two groups? Yes or no. If the conclusion is ‘reject the null’ then there is a significant difference. If the conclusion is ‘fail to reject the null’ then there is no significant difference. End of Lab J
