Compare & contrast the Graphs from your OWN Group’s data and the CLASS Groups’ data. Give one (1) similarity that you observed between them ? Give one  (1) difference that you observed between them ? What do the similarity and difference mean when considering reliability and validity (include Standard Deviation in your answer)?  

Of the two known bacteria that were stained in the in the questions above, which one was Gram positive and which one was Gram negative? E. coli = ________ [1] _________Staph = ________ [2] _________ 

Your task in this lab was to stain two bacterial samples.  In the picture below, make the correct identification of the Gram stain of Escherichia coli (E. coli) cells viewed under the microscope : Escherichia coli (E. coli) – The Gram reaction for this bacterium is [1] and the shape of this bacterium is a [2]. 

The process of evolution results from four known factors, for each listed, describe how those factors were observed in the wolf/rabbit simulation.   Factors that result in Evolution Observations Variation  (individuals have different traits)   Inheritance (traits are inherited)   Differential survival and reproduction (some individuals have traits that help them survive and reproduce)   Adaptation/Advantageous Trait (the frequency of that trait increases in the population)  

When observing Elodea cells you notice the presence of [a] that indicates this is an [b] organism and it is [c]. Then, you classify the Elodea as a plant because its leaf’s have [d], numerous [e], a visible [f] – these features help us get started on classifying them as plants.

BONUS [2 points] – bonus points will be entered manually if you chose the correct answer! How does the sensitivity (susceptibility) of the Staphylococcus aureus compare with the sensitivity (susceptibility) of the E. coli? [Hint: Look at the Penicillin antibiotic disk]. Mark the correct conclusion:  

See information provided in Canvas and feel free to do your own research to fill in the blanks and answer the question below.   QUESTION: How are bacteria able to develop resistance to antibiotics so quickly? ANSWER: Bacteria multiply [1] which allows for rapid changes in the population. Antibiotics kill off the more susceptible (sensitive) but [2] the more resistant bacteria. This [3] the percentage of resistant bacteria in the population. As these bacteria increase in number, they increase the resistance of the population to the [4].    

Using a metric ruler, measure the Zone of Inhibition in mm (round up to the next millimeter), and record the measurements in the table blanks below.  Based on the ‘Zone Diameter Interpretive Table’, indicate the degree of sensitivity of the bacterium [resistant (R), intermediate (I), or susceptible (S)] to each antibiotic tested. Bacterial species tested: Staphylococcus aureus.  Table for results of the measurements of Z.I. Antimicrobial Zone Diameter (mm) Sensitivity P10 [1] [7] SXT [2] [8] NB30 [3] [9] E15 [4] [10] N30 [5] [11] TE30 [6] [12]    

In the space below, please provide examples from the discussion that show a quality claim, procedure, result 1, result 2 and conclusion.  You may pull directly from a classmates, but be sure to cite your source.    (Claim:…. (John Doe, accessed Feb 2, 2023); Procedure: … (Jane Smith, accessed Feb 2, 2023), etc).    If you can’t find a quality example of each you may reword examples until you think it meets the requirements.  Make sure you use the rubric to help guide your answers.  If you upload make sure it is a doc, docx, jpg, or pdf.

BONUS [up to 2 points] – bonus points will have to be entered by hand. Answer Question #A: Observing the plates pictures in the Simulator: Which of the three Kirby-Bauer Test plates shows evidence of the increased number of cases of bacteria resistance to antibiotics ? Choose one and fill in the blank:  E. coli, or  P. aeruginosa, or  S. aureus. (Spelling counts).
