Need help with what the classification is and Q3 & Q4.
Read Exercise 2-9 in your lab manual, then complete the following items. 1. This week you will use a spectrophotometer to determine the optical density (absorbance) of the temperature tubes you inoculated last class. Describe the relationship between absorbance and growth briefly. •More bacteria that grew, higher 2. Plot the following data on the graph provided, correctly label the X and Y-axis, draw a trend line, and then list the temperature classification of the organism in the space provided. (4 pts) Growth of Unknown "Sparky 3415" in NB Broths 'C 10 20 30 40 50 Classification: Absorbance @600nm 0.35 0.65 0.75 0.80 0.65 1 0.8 0.6 0.4 0.2 0 Growth of Unknown "Sparky 3415" in NB Broths 10 2D 3D 4D 5D Temp.(C) Read Exercise 2-13 and 10-5 in your lab manual, then complete the following items. 3. What molecule in the bacterial cell does the UV radiation effect when exposed? What is the most lethal wavelength of UV radiation? List UV radiation's specific effect (mode of action) on a bacterium that ultimately causes the microbe to die. (3 pts) 4. Figure 2.53 illustrates how you will expose your bacterial cultures to UV radiation. Assuming you've treated your plates with a lethal dose of radiation, describe where on the plates you will and will not expect to see growth in relation to the position of the cardboard shield.
