match the bacterial classification with its correct description:

1. ___ obligate aerobe
2. ___ obligate anaerobe
3. ___ microaerophile
4. ___ aerotolerant anaerobe
5. ___ facultative anaerobe

a. cannot survive in the presence of oxygen.
b. requires oxygen but at lower levels than atmospheric concentration.
c. can grow with or without oxygen but prefers oxygen.
d. requires oxygen to grow.
e. does not use oxygen but can tolerate its presence.

Explanation:

Obligate aerobes need oxygen to grow. Obligate anaerobes cannot survive in oxygen. Microaerophiles require oxygen but at lower - than - atmospheric levels. Aerotolerant anaerobes don't use oxygen but can tolerate it. Facultative anaerobes can grow with or without oxygen but prefer oxygen.

Answer:

1. D. Requires oxygen to grow.
2. A. Cannot survive in the presence of oxygen.
3. B. Requires oxygen but at lower levels than atmospheric concentration.
4. E. Does not use oxygen but can tolerate its presence.
