Here’s your Shmoop du jour, brought to you by stings.
- 00:07
Not those stings. The kind that hurt. With venom, not with love songs…
- 00:13
Here’s a passage about an experiment performed on the communication of honey bees.
- 00:22
And our test question:
- 00:24
The scientists decide to run a chromatogram on air outside the hive.

What would you expect the chromatogram to look like?
- 00:33
Here are your potential answers…
- 00:40
What would a chromatogram from outside the hive look like?
- 00:44
We’ve already got 2 examples of chromatograms in the graphs above, but
- 00:48
neither of them were taken outside the hive. Let’s take a look.
- 00:52
Figure A, shown here, was taken inside the hive at the dance floor, where bees were dancing
- 00:57
and releasing certain compounds that are indicated by peaks A through D.
- 01:09
Figure B was taken inside the hive, but away from the dance floor.
- 01:13
The lack of peaks is from the lack of waggle dance compounds being released there.
- 01:21
So what might we get from a chromatogram taken outside the hive entirely?
- 01:25
Well, we can assume that since bees only perform the waggle dance in one specific area inside
- 01:30
the beehive, we probably won’t be seeing those waggle dance compounds on the chromatogram.
- 01:34
That means no peaks.
- 01:37
The only possible answer that fits that assumption would be B:
- 01:41
“It should lack peaks A through D”
- 01:44
Our answer is B, as in Bee stings.
- 01:47
Guys, no, come on, we’ve been over this.
