You are working in the lab with Streptococcus pyogenes and two other bacteria. You streak all three of these microbes onto a Blood Agar plate and observe the following: All of the bacteria grow on the plate but there is a large zone of clearing around S. pyogenes, and no zone of clearing on the other two bacteria. Based on these results what type of Medium is Blood Agar? A) Blood agar is a culture medium. B) Blood Agar is a selective medium. C) Blood agar is a differential medium. O D) Blood agar is an exclusion medium.

These are members of the prokaryote kingdom. They live in water, air, soil, and all-natural environments. They are used in industrial and therapeutic processes, and they support a wide range of plant and animal life. The first organism to appear on the planet.
