question 1\nwhat is the gram nature and morphology of this organism in the picture?\n○ gram negative coccus\n○ gram negative bacillus\n○ gram positive coccus\n○ gram positive bacillus

Answer

Brief Explanations:

  1. First, recall Gram - staining principles: Gram - positive bacteria retain the crystal violet stain (appear purple), and Gram - negative bacteria appear pink/red after counter - staining. In the image, the bacteria are purple, so they are Gram - positive.
  2. Then, analyze morphology: Cocci are spherical, bacilli are rod - shaped. The bacteria in the image are spherical (coccus - shaped). So combining these two observations, the organism is Gram positive coccus.

Answer:

C. Gram positive coccus
