What does a positive result of a bacterial "catalase" test look like? What's in it that makes it look like so? Select one: O a. The small clump of bacteria appear at the bottom of the tube of test broth. The color of the broth turns deep red, showing acidic substance is being secreted by the bacteria b. The small clump of bacteria makes bubbles/ foams, and it is oxygen gas that's in the bubbles O c. The agar turns...

As a means to confirm diagnosis, TCBS agar (Thiosulfate-citrate-bile salts-sucrose agar) is used to grow Vibrio cholerae from patient samples The recipe for this growth media is shown below. Based on this information, which of the following statements accurately describe this media? Select all that apply. (NCLEX-HESI-TEAS style) This media is considered a complex agar. This agar is selective. Bromothymol blue and thymol blue contribute to this agar's use as a differential media. Prior to inoculation, the agar is likely...

Two different types of injection-molding machines are used to form plastic parts. A part is considered defective if it has excessive shrinkage or is discolored. Two random samples, each of size 300, are selected and 15 defective parts are found in the sample from machine 1 and 8 defective parts are found in the sample from machine 2. What type of hypothesis test should you use to determine if both machines produce the same fraction of defective parts? Group of...

A) Test the claim that the two samples are from populations with
the same mean.
What are the null and alternative hypotheses?
1)P Value
2)Test statistic
3)state the conclusion for the test
b. Construct a confidence interval suitable for testing the
claim that the two samples are from populations with the same
mean.

How would you test the affect of metal salt (activator) on catalase (an enzyme)? What would the procedure look like and what are the materials that would be needed? In this specific lab, ginger and banana extracts are being used as the catalase concentrations.
