Question

some bacteria can divide as quickly as every ______ minutes.
a 2
b 200
c 60
d 20

Explanation:

In microbiology (a subfield of Biology, which is under Natural Science), some bacteria, like E. coli under optimal conditions, can have a generation time (time to divide) of around 20 minutes. 2 minutes is too fast for most bacteria, 200 minutes is too slow, and 60 minutes is longer than the typical rapid division time for fast - dividing bacteria. So the correct option is d.

Answer:

d. 20
