Casey, a microbiologist who has extensively observed Escherichia coli (E. coli), wants to compare the death phase growth curve of E. coli after exposure to three different antibiotics: ampicillin, ceftriaxone, and levofloxacin. Determine the order in which Casey plans and implements a comparative investigation. Rank the steps in the order in which they should occur in a scientific investigation. The first step should be placed in the highest position, at step 1, and the last step should be placed in the lowest position, at step 6. a. Casey reads background information on E. coli, the selected antibiotics, and other similar studies.
b. Casey publishes the results and conclusions in a scientific journal.
c. Casey takes bacterial counts every four hours after samples are exposed to one Of the three different antibiotics.
d. Casey develops a scientific hypothesis and designs an investigation to test it.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
