Have you ever wondered what infections look like from the pathogen’s perspective? If our immune systems are so amazing, why do we get sick at all? During this simulation, you’ll undertake a series of challenges in preparation for an important global health investigation. Can you complete each task and add to the planet’s immunological understanding?ActivityResearch and answer the following questions:How does the immune system protect against pathogens?What are the similarities and differences between the innate and adaptive immune systems?What is immunological memory and why is it important?This assignment should be 2–3 double-spaced pages in APA (7th ed.) format and have at least one outside resource. Be sure to cite your resources.

InstructionsReading scientific literature is important in professional development for anyone in the medical field. However, reading research articles and scientific articles can be challenging. This activity will reinforce your understanding of microbiology, as well as teach you how to read, comprehend, and apply concepts useful for microbiology.ActivityRead the following articles:”How to Prevent the Spread of Respiratory Illnesses in Disaster Evacuation Centers” (Links to an external site.)Citation: CDC: Center for Disease Control and Prevention.

Travel Medicine, 561–572. https://doi.org/10.1016/b978-0-323-03453-1.10057-4Answerthe following questions in 1–2 double-spaced pages following APA (7th ed.) format.How are the majority of respiratory diseases spread?Identify three important control measures to help decrease the spread of respiratory disease? Which of these measures is most effective in your locale?Identify two diseases from the articles that you found most interesting. Explain.

The Role of Diversity in Public Health WorkFor this discussion, analyze how your proposed project acknowledges the value of diversity in your attempt to address or solve a public health problem. Consider the information shared from the What Is Diversity? multimedia piece from this unit’s study and discuss the possible cultural difficulties in this project. How do you anticipate overcoming those difficulties?

Go to the EPA website and learn about “Reduce, Reuse, Recycle”Are any of these options and/or types of programs available in YOUR local community/village/town? Which ones? Explain.What about in your home? Explain.If none are used in your local town or home, which could be? Explain.Please outline in your own words, one new thing you learned this week in the course. How does it apply to your life?Tell me, the professor, how this course is going for you so far? How do you find the material?

A journal reports on a food service management topic are required. Articles pertaining to food service management must be used; be sure to check they come from professional journals or peer-reviewed journals. Followed the template that I have uploaded.

Aseptic Techniques Name ———————–20 ptsObjectives1.- Be aware of where bacteria can be found, and what are the environmental factors that influence the growth of bacteria.2.- Understand the process and importance of labeling and incubating agar plates properly.3.- Learn the aseptic techniques practices necessary to prevent cross-contamination4.- Identify growth of bacteria on the surface of an agar plate, a nutrient broth, and an agar slant.5.- Use colony number estimates to reach conclusions about amount of bacterial growth.6.- Determine the effects of handwashing on bacterial abundance. Determine the effects of bench disinfection on bacterial abundance.7.- Define: pure culture, contamination, aseptic techniques.8.- Know the characteristics of broth medium, bacterial slants, and agar plates.9.- Identify the steps of transferring from broth to broth, slant to slant, and broth to plate.1.- Introduction (4.0 pts.)1.- ( 1 pt.) Explain the following conceptsWhat does the phrase ‘bacteria are ubiquitous’ means?What is media?2.- ( 1pt.) List two locations in a laboratory where bacteria can be found.List two places, in a laboratory, where bacteria should never be found.3.- (1pt.) The first step in working with any type of medium, is to label it properly prior to use.Why are agar plates always labeled at the bottom?Agar plates are always incubated upside down. Explain why.4.- (1 pt.) Incubation temperatures are always given in degree Celsius. The standard incubation temperature of bacteria isolated from human specimens is:Incubating bacteria, isolated from human specimens, at lower temperatures will slow down their growth. Give the approximate temperature (in degree Celsius) of the following incubators:Room temperature incubator:Refrigerator temperature incubator:2.- Ubiquity Exercise (5.0 pts.)In this exercise bacterial presence was investigated in four different environments: banana, soda can, keyboard, and cash.1.- (0.5 pts.) What implement was used to collect the bacterial samples from the 4 different objects?Name the type of medium used in this exercise to grow the bacteria.2.- (1 pt.) Mention two steps that prevented cross-contamination during this exercise.3 .- (1 pt.) During this exercise, what does it mean to ‘streak a plate”?What is a ‘colony’? Are all colonies alike?Where was the cotton tip discarded after each use?Do you think that the medium used to dip the cotton tip was sterile? Explain your answer.4.- (1 pt.) ***Take a picture of the results obtained and upload the picture onto your lab report.4.- (continuation) Complete the table below with the results of the exercise. Note in the chartunder ‘Colony variety’ whether the colonies growing on each plate all look the same, or if there are variations in size, consistency, and color.NUMBER OF COLONIES PER PLATEPLATE LABELAmount of bacteriaColony variety seen/not seen5.- (0.5 pts.) Using the results obtained, explain how handwashing affects bacterial quantity and diversity.6.- (0.5pts.) Using the results obtained, determine which of the 4 objects (soda can, banana, keyboard, and cash) tested had the most amount and variety of bacterial growth. Were the results expected?7.- (0.5pts.)

Be sure that you can explain what the image is showing. Identify all anatomical structures in the image as appropriate. Discuss whether this disease or disorder is something that is more or less prevalent within a specific age group across the lifespan. Also, make a brief statement about how the homeostasis of the body can be impacted by this disease.
