- 8. Pigment or color (e.g.: opaque, translucid, red, yellow, rose, violet, etc..) is also another characteristic that can be used to identify your microorganism in a slant. Thus, write down the name of three microorganisms (using scientific notation: Escherichia coli) that present a pigmented pattern of growth in a slant (write down the color of each pigment) and the name of the disease that they may cause. 200%- 927 PM 0 日 2/7/2021 21 DELL Insert Delete F11 F12 PrtScr F9 F10 F7 F8 F6 F3 F4 F5 Esc F1 F2 Backspace & # 2$ 8 4 1 2 P Home R T E Enter K Shift V B Page Down Page Up Alt Ctrl Alt THome ノ/ *00 ΣPulverizing dry ingredients into a fine powder is called Select one: O a. penetrating O b. levigating O c. suspending O d. homogenizingIf you were tasked with developing a treatment plan consisting of the spraying of Btk (Bacillus thuringiensis kurstaki).

- 2) Assume that you made an error during your staining procedure. You used safranin as the primary stain and malachite green as counterstain. How would your cells appear at the end of the staining of the staining technique?1. A student is directed to make a simple stain of coli with crystal violet, but got mixed up and used safranin instead. How would their observations be different? Would the information obtained be any different? 2. How is the procedure different when taking cells from a solid medium compared to taking cells from a liquid medium? Why is it important that your smear be thin?3. You were instructed to add 2.75 mL out of 5.0 mL of an undiluted sample to 125.25 mL of sterile diluent. Instead, you add all 5.0 mL to the 125.25 mL, What was the intended dilution and what was the actual dilution? ited States) E Focus OCT 30 W MacBook P DII DD F7 F8 F9 F10 F4 F5 F6 F3 2$ 4 081 R F G H.
