After completion of a Gram stain procedure, you notice the bacteria cells shown in the picturebelow. How would you categorize the bacteria based on 1. Gram stain results, 2. Cellarrangement, and 3. cell shape.?Would the bacteria in question 7 have a thick layer of peptidoglycan or a thin layer ofpeptidoglycan in its cell wall?Would the bacteria in question 7 have an outer lipopolysaccharide layer in its cell wall?Would the antibiotic penicillin likely work to eliminate infection with the bacteria in question 7?How would you describe the type of flagella arrangement for the bacterium below? (You'll useone word for the description here.)

A lab technician is working with a bacterium in pure culture (in 5 ml of liquid media in a test tube). The bacterium is a mesophile that can infect humans. Which of the following is NOT true (with regards to temperature conditions for this bacterial culture)? Lowering the temperature to -10 deg C for at least an hour will likely kill all the bacteria. Placing the tube at 37 deg C will likely facilitate rapid growth of the bacteria. Raising the temperature to 90 deg C for at least an hour will likely kill all the bacteria. Placing the tube at 4 deg C will likely slow or halt growth of the bacteria.
