You are tasked with enumerating the viral load of an unknown sample. You begin your investigation by serially diluting the sample resulting in the following dilutions: 10-2, 10-4, and 10-6. You spread 80µl of each dilution onto a separate nutrient agar plate and incubate for 48 hours. Upon examining the plates for the 10-2 and 10-6 dilutions only. You observe the following results:  10-2: 125 PFU  10-6: 90 PFU  Calculate the phage titer for these two agar plates. Report your final answer in the correct notation and with appropriate units.

According to Jiang (2021), what is defined as a sudden and substantial increase in workload such as during unexpected catastrophic events?

According to the lecture, meaning in life is made up the following components, EXCEPT:

According to chapter 15 of your textbook, what are the foundational components of positive schooling?

After performing Gelatin Hydrolysis test on two different organisms in separate test tubes labeled 1 and 2, you observed the results. a) Which test tube shows positive result 1 or 2?  b) What enzymatic process does gelatin hydrolysis test for? c) Why do we use an ice-bath in this test?   

According to chapter 15 of your textbook, which of the following are ways you can help teachers and the school system?

You are performing the following biochemical test for the unknown bacterial isolate. Identify the name of the test and describe the enzymatic process responsible for the color change.

According to the lecture, this term refers to how important work is to a person’s life, and affects how job satisfaction relates to life satisfaction

You perform a serial dilution series of the same species of bacteria onto identical agar plates, all incubated for 24 hours at the same temperature. Shown from upper left to lower right are bacterial dilution concentrations of 10-2, 10-4, and 10-6. Given that the agar plates and bacterial sample were identical before diluting, what is the best explanation for the difference seen in bacterial colony size amongst the three plates?
