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.

00:30

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.
