Bonus (+1 each) Select all of the responses that indicate the importance of the Gram stain. Gram stain results can help classify bacteria. Gram stain results can help classify yeast. Gram stain results can assist in diagnosing bacterial infections. Gram stain results can assist in choosing an appropriate drug treatment. Gram stain results are no longer useful in medicine. Bonus (+1) What role does crystal violet play in the Gram stain procedure? primary stain secondary stain...

You are in microbiology lab and are approached by another member of the class who asks you to help him with a Gram stain. He tells you that he has performed the first 4 steps of the procedure (as shown in Fig 2.22 of the Slonczweski textbook) but just remembered he needs to make an important phone call and asks if you will complete the procedure as he is running out the door. You complete the procedure for him but...
