! Required information The concentration of E. coli bacteria in a swimming area is monitored after a storm: t (hr) 4 8 12 16 20 24 c (CFU/100 mL) 1600 1320 1000 890 650 560 The time is measured in hours following the end of the storm and the unit CFU is a "colony forming unit." Employ the given base-10 model to estimate the concentration at the end of the storm (t = 0). y = α5 105x (Round the final answer to three decimal places.) The concentration at t=0 is 1985.437 CFU/100 ml.

- Opioid dependence is described in the Australian Medicines Handbook as a chronic, frequently relapsing illness. One approach to managing opioid dependence is opioid substitution therapy (opioid maintenance therapy). The figure below depicts concentration-response curves for two drugs used in the management of opioid dependence compared to heroin: 100 LEGEND 60 U 20 0 0.0001 0.001 0.01 0.1 1 10 [Drug] (Log Units) Question: From the drugs listed below, select the options that are most likely to be represented by the concentration-response curves for: Drug A: Drug B: Buprenorphine Naloxone Methadone Naltrexone % Maximal Response 100 Heroin Drug A Drug BYou are creating a standard curve for a protein experiment. You have to stock solution of BS a and would like to obtain dilutions. Explain how you would create a 1:1000 dilution of your protein stock solution.Given the Ksp for Ag2CrO4 is equal to 1.20 x 10-12, calculate the percent error in your experimentally determined value for average Ksp (this will be an extremely large percentage – think about why).
- 1) Listen -5 The Ksp value for calcium sulfate [CaSO4] is 2.40 X 10 and a professor made 1825 mL of a CaSO4(ag) solution but then one of his graduate student accidentally poured in a 0.125 M solution of calcium phosphate [Cag(PO4)2] solution. You may ignore the additional volume coming from the Ca3(PO4)2 solution to make the calculation simpler.

Mom brings in her 3 year old little boy, Brandon. Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby! He's also been pulling a lot at his right ear and sounds congested. At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg. Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips. His temperature is 39C, other vitals signs are normal. Though he looks ill he appears to be medically stable. The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom. The orders include: push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…During a routine check of the fluoride content of Gotham City's water supply, the given results were obtained from replicate analyses of a single sample: 0.815 mg/L, 0.789 mg/L, 0.811 mg/L, 0.789 mg/L, and 0.815 mg/L. Determine the mean and 90% confidence interval for the average fluoride concentration in this sample. Report the mean and the confidence interval using the "real rules" for significant figures. mean: 0.804 90% confidence interval: 2.32 x10-4 Incorrect mg/L mg/L
- You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.Dr. TS You found lead in blood collected from children living within 5 km from the Ship Channel.
