- Food is often irradiated with either x rays or electron beams to help prevent spoilage. A low dose of 5–75 kilorads (krad) helps to reduce and kill inactive parasites, a medium dose of 100– 400 krad kills microorganisms and pathogens such as salmonella, and a high dose of 2300–5700 krad sterilizes food so that it can be stored without refrigeration. (a) A dose of 175 krad kills spoilage microorganisms in fish. If x rays are used, what would be the dose in Gy, Sv, and rem, and how much energy would a 220 g portion of fish absorb? (See Table 43.3.) (b) Repeat part (a) if electrons of RBE 1.50 are used instead of x rays.Please provide evidence supporting or refuting the following statement: Humans consume microbes every day with little health risk.a.) Infection with this pathogen can result in a wide range of diseases from ear infections to meningitis. Group of answer choices Haemophilus influenzae Francisella tularensis Enterococcus faecalis Naegleria fowleri b.)As with all microbial control methods, the _______ the cells are exposed, the ______ damage accumulates. Group of answer choices longer, less shorter, more longer, more c.) Which of the following wavelengths would NOT be considered ultraviolet radiation? Group of answer choices 360 nm 200 nm 600 nm 25 nm
- Question 1 Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You’re concerned that it’s an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium or a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. What is one experiment you could do, involving culturing the organism? Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we have done/could do in our lab. What is a procedure you could do, involving making a slide of the organism? Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we have done/could do in our lab. Without testing anything, how do you know this is not a viral infection?A drug failed to work. Even if resistance is not an issue, the antimicrobials are found to only have a discrete range of bacteria that they can exert their effects on. Why is this the found case? Question options: Microbial components vary over different species and strains. If the organism naturally doesn't express the target component, the drug won't be able to exert an effect on it. Antimicrobials are designed to be effective for a predetermined period of time. An older antibiotic can't exert any effects on a new microbial strain. There is a different antimicrobial designed for every strain of bacteria. As a result there is no crossover in action due to selective targeting. The body filters antimicrobial compounds to interact with their target microorganism. Until research determines how to control this, antimicrobials will only ever have a very discrete range of targets.How would you use the FEMA Model (four phases) to respond to a potential chemical spill at the Beatrice plant?
- Please answer all questions!! Choose a specific process in food businesses that allow them to get rid of/prevent the growth of microbes on food. How is it used commercially? Is it common? What are the specific guidelines associated with that process? Do they take any safety precautions? If so, what are they? Why is this process important to society? Please answer all questions in detail! For example, how do they tackle E. coli being on produce?? I need a specific example of what can get rid/ prevent those types of microorganisms.Which of the following types of data produce curves similar in shape to the graph? Select all that apply 1.Bacterial growth in a culture 2.A normal distribution of height in a population of students 3.Exponential population growth 4.Haemoglobin binding of oxygen 5.Log transformations of drug dose curves 6.Osmotic fragility of red blood cells 7.A standard curve for an enyme assayUse this graph showing the standard death curves of three microbial species to answer the following two questions. The three microbial species shown in the graph where all treated at 70° C. If you had to sterilize a food product that contained 107 bacteria, how long would it take for each bacterial species? Calculate the D70 values for these three bacterial populations. For the next three questions, assume D90 = 22 minutes. At what temperature will you treat a food product? How long does it take you to kill 90% of bacteria? How long will it take you to sterilize a food product if it had 109 bacteria on it? Serial Dilutions 6a. A sample is given to you that contains 6 million cells per ml. You must make a series of serial dilutions in order to get a countable number on a plate to prove that there are indeed 6 million cells per ml. The plate that you eventually put a sample of bacteria on must have between 10 and 100 colonies for ease of counting. What…
