You are a field researcher for the CDC. You and your lab partner have been sent to an area to quantitatively analyze a set of samples believed to contain pathological bacterial contaminants.
On a separate sheet of paper, write (NEATLY) or type the procedure you used to quantitatively analyze the given bacterial suspension. Include steps in the procedure and materials used (5.5 pts). Be organized, logical, and neat in documentation of this information.
Write your results. Show your work. No Work No Credit (1.5 pts).
Total Count = _________
Viable Count = _______
% Viability = _______
The amount of 250 CFU per 0.01 ml is considered harmful to humans and other animals. If your sample contains close to or more than an excessive amount of bacterial contaminant, what can be done to decrease the numbers of bacteria without harming humans or animals (3pts). How would you know if your method of decreasing the numbers of this potentially harmful bacteria? * Hint* What needs to decrease? Total Count or Viable Count? Why?

Background:
You are a CDC (Center for Disease Control) researcher studying
malaria. Your goal is to understand the evolution of malaria in
order to be able to possibly predict where a future outbreak may
be. To do this you will be using information from the evolution of
the pathogen, the host, and changes in the environment. Topics to
think about include:
What is the evolutionary origin of human malaria? (hint: think
about host-pathogen cospeciation or host shift)
What could you...

Pretend you and your lab partner are designers for the PhET
simulations and want to make a simulation for students to
investigate gravity fields. Think about what you know about gravity
and what kinds of experiments a student might want to do to learn
about gravity. You may have to refresh your memory by using the
text. Draw a design, by hand, for a gravity simulation. Explain why
you included each component and explain at least one experiment
that a...

You are a lab manager and you have been informed that your
Laboratory received funding for high-end automation: you will have
an automated specimen processing belt that will allow you to sort
specimens, centrifuge them if need be, deliver them to Chemistry
and Hematology sections of the laboratory, load them into the
analyzer and then store them post-processing.
Post your responses to each of the following:
1. What approach would we take to lead this change? Please
explain your answer....

You are an executive of an American company. You have been sent
to South Korea to expand your company’s operations in that
country.
(a) From your knowledge (or research) of cultural differences
between the South Koreans and Americans, what two
cultural mistakes are you likely to commit in South Korea that
would irritate the Korean people?
(b) What can you do to minimize chances of making those cultural
mistakes, so that you can be more successful in South Korea?
