IMPORTANT!!! Please answer it precisely. It is expected to use academic knowledge and language. Use your own words, do not copy paste.

Suppose you are a microbiologist living in late 1800ies and early 1900. You suspect that the microorganism called Mycobacterium leprae might be responsible for the disease called leprosy. You had heard about a researcher called Robert Koch and his postulates, and you would like to follow his approach to test if leprosy is caused by Mycobacterium leprae. Explain stepwise and in detail the experimental procedure that you would follow. Please also explain what kind of results you would expect in each step of your procedure.

Please explain in detail how the microbiology information about the infectious diseases and their epidemiology, aseptic techniques of microbiology (sterilization, disinfection, antimicrobial techniques and agents) helped you during the COVID-19 pandemic. Please give detailed examples of how you used your microbiology and/or scientific knowledge in helping/informing people in your family and/or your community and/or how different was your behavior and attitudes than the others (non-microbiology/molecular biology people) around you during the COVID-19 pandemics and the lockdown period.

Pick one of the two options below Option 1: Mini-Mental Status Examination The Mini-Mental Status Examination, originally developed by Folstein, Folstein, and McHugh (1975) in the Journal of Psychiatric Research, vol. 12, pp. 186–198, in the original or revisesd form is commonly used to conduct a quick assessment of dementia and overall mental functioning. Pick four of the main questions and discuss how the answers you might receive from a person might differ if a) the someone appears to ahve h no cognitive impairment versus b) a perosn shows mild cognitive impairment versus c) a perosn shows severe cognitive impairment? Discuss the advantages and limitations of the MMSE? Do not simply quote or paraphrase your references - explain what you learned in your own words. Option 2: Head Injuries Research and read at least two peer-reviewed articles on the topic of head injuries and mental health problems related to sports (football, full contact martial arts, boxing, etc.) or from accidents or combat injuries. Include any issues related to co-morbidity that you found or that you would expect might occur. Describe/summarize what you found in terms of symptoms. How might these symptoms mislead or confuse a mental health practitioner when assessing a patient and about making a diagnosis, for example: a professional assumes a mental disorder (i.e., a depression, bi-polar disorder, personality disorder, etc.) is the main issie, not realizing a person has an unstated history several mild to moderate head concussions, or a history of severe seizures, or a single severe episode of head trauma.

  • Describe TWO specific cellular mechanisms through which a bacterium can become resistant to an antibiotic. Please note that this question is NOT about practices or actions we do that contribute to antibiotic resistance in bacteria, such as not taking the entire prescribed dose. Please remember that bacterial cells become resistant or tolerant to antibiotics, NOT human cells, or the human body. *** Perform some research in the college's online library, a microbiology textbook, and other credible scientific sources of information.
  • Explain the concepts of mutation and natural selection as part of the development of antibiotic resistance in bacteria.
  • What are two or three actions that we, as a society, can take to limit or reduce antibiotic resistance in bacteria?

Draw the ‘length-tension relationship’ curve for left ventricular function i.e. Stroke Volume (SV) versus End-Diastolic Volume (EDV). Use this to explain the Frank Starling mechanism and explain how the autonomic nervous system can affect this curve.
