When we scan the answer choices (ALWAYS scan the answer choices BEFORE deciding on the approach you'll take), we see that the number of population "doublings" will be between 5 and 9.BTGModeratorVI wrote: ↑Sat Aug 08, 2020 7:05 amThe population of a bacteria culture doubles every 2 minutes.

Given these relatively small values, we might solve this question by creating a growth table
MINUTES ELAPSED | POPULATION
0 | 1,000
2 | 2,000
4 | 4,000
6 | 8,000
8 | 16,000
10 | 32,000
12 | 64,000
14 | 128,000
16 | 256,000
18 | 512,000 DONE!!
Answer: E
