A scientist is doing research to understand how volatile hydrocarbons affect phytoplankton (algae) growth during oil spills. In the lab, he adds a constant amount of oil and different levels of a volatile hydrocarbon (0- 50 μg/ml) to phytoplankton in salt water with nutrients, trace minerals and sodium carbonate buffer. The scientists uses a spectrometer to detect the level of algae in the tube. In this way he can see growth of algae. Independent factor: volatile hydrocarbons Dependent factor: Algae as detected by absorbance in a spectrometer What belongs in the control? Select one or more: Sodium carbonate buffer Volatile hydrocarbons Water Algae Salt Oil Trace minerals Nutrients.

Question:- Two different patients suspected of having a urinary tract infection submitted fresh urine samples to a lab for culture and antibiotic sensitivity testing. The samples were inadvertently left out overnight at room temperature. The next day, a medical technologist discovered the samples. Upon opening the first sample, the strong smell of ammonia was noticed. The second urine sample did not have a strong ammonia smell. Based on these observations, which urine sample most likely contained cells of the bacterium Proteus Vulgaris? Explain your answer. If these two urine samples had not been noticed until a week later, would you expect there to be a difference in the “odor” of the samples? Explain your answer.

Support your answer using computation-based judgment. Encircle/box your final computed answer in your solutions along with a declaration of TRUE or FALSE for each given situation. Milk sample A contained an average of 53 cells per FOV at a dilution factor of 7 whereas Milk sample B contained an average of 99 cells per FOV at a dilution factor of 5. Therefore, milk sample A has less microbial contamination. (Note: 0.01mL of each sample was placed on a clean glass slide and both samples were examined under OIO with an area of 1.77x10-4 cm2.)
