Would heating the culture in a sealed, small-diameter tube that is totally immersed in a water bath produce more accurate results than the use of tubes that are partially submerged in a water bath? Give reasons for your answer.

Draw what is happening in a microtiter plate well when the patient's sample contains TSH. Provide a key to your drawing.

True or false  A spectrophotometer is used to directly count the number of cells in a liquid culture media.

Your first task in the lab is to learn how to culture these cells and begin expanding the culture (increasing the # of cells) so that you may later conduct experiments on them.  You take two aliquots, each with an equal number of cells, and place them in two different culture vessels, one is a sealed airtight flask (culture 1) and the other is an open topped culture dish (culture 2). You provide both with the same growth media that contains their preferred fuel source, glucose.      Are the cells in cultures 1 and 2 deriving all their energy in the same way?  (Yes or No) Explain why or why not.  Be sure to name the specific processes by which each culture is deriving its energy.

If you plated 0.1mL of a 103 dilution and you obtained 235 colonies on your agar plate, how many CFUs per mL were in your original sample? If a bacterium can divide once an hour, then after 5 hours, 1 bacterium will have yielded ______ bacteria
