Question

question 1 (bonus) (1 point) blood agar is considered a differential medium because it shows hemolysis patterns. true false question 2 (1 point) what is the main purpose of using differential media in microbiology? to make all bacteria appear the same to prevent all bacterial growth to encourage bacterial motility to distinguish between bacteria based on metabolic characteristics

Explanation:

For Question 1: Blood agar can show different hemolysis patterns (alpha - hemolysis, beta - hemolysis, gamma - hemolysis) which helps in differentiating bacteria, so it is a differential medium.
For Question 2: Differential media in microbiology contain specific substances that allow certain bacteria to exhibit characteristic reactions based on their metabolic abilities, enabling differentiation between them.

Answer:

Question 1: True
Question 2: to distinguish between bacteria based on metabolic characteristics
