What are categories of medical interventions?46101002095500Describe the ELISA results shown. 461010055880Positive Negative Patient A Patient BControl Control 00Positive Negative Patient A Patient BControl Control When treating this outbreak a pharmacist is asked to fill a prescription for an antibiotic medication and performs a serial dilution. She places 25 ml of the antibiotic and 100 ml of saline in a mortar and blends the mixture.??This is Sample A.??She then transfers 50 ml of this dilution into another container with 100 ml of saline; this mixture is Sample B. Lastly, she transfers 75 ml of this dilution into a container with 100 ml of saline; this mixture is Sample C. Using spectrophotometry, she determined the concentration of Sample C is 5 x 10-3 g/mL. Draw a diagram of the serial dilution she performed. What are the tube dilution, final dilution, and antibiotic concentration for Sample A, B, and C? Create the resulting DNA gel, horizontal chromatogram, and vertical chromatogram given the following sequence and the left primer: CTGG and right primer: GGT. GATCTGGAGATTAGTGGAGGTCATGGACC 1.2: Antibiotic TreatmentDraw and label a bacterial cell with the appropriate structures. What are two reasons why gram-negative bacteria are different than gram-positive bacteria?585089014922500How is a zone of inhibition test conducted? Based on the figure, the bacterium is most susceptible to which antibiotic? Describe the three methods of horizontal gene transfer. 1.3: The Aftermath—Hearing Loss433070010604500Label the diagram, then explain the path of sound from generation to perception. 440055012890500Based on the audiogram provided, what is an appropriate prognosis and medical intervention for the patient? 1.4: VaccinationHow do vaccines activate the human immune system? Why are restriction enzymes and ligase important in making recombinant DNA vaccines?An epidemiologist wants to perform a study to determine if exposure to CT scans causes an increased incidence of cancer. The individuals chosen for the study are people who have been exposed to CT scans and people who have not been exposed to CT scans. What type of study will be performed – a case control or a cohort? Explain your answer.Unit 1 MI: How to Fight Infection Test Study Guide—Test Friday October 30th, 2015 (37 MC, 2 of 3 Short Answer)What is a medical intervention?
