Ants. Ugh. Filthy little creatures. Always climbing all over your PB&J sandwich and getting
- 00:39
into the crevices of your cherry pie.
- 00:42
So why have some scientists spent some of their valuable time messing around with these pests?
- 00:47
What's the purpose?
- 00:50
Let's start by looking at the data collected.
- 00:52
What does the graph show? Well, it shows the percent of transported leaves.
- 00:58
What does that mean though? Well, to find out, we have to take a look at the apparatus.
- 01:02
Why is the experiment set up like this? Other than because the scientists are sadists who
- 01:07
enjoy watching ants fall from great heights.
- 01:10
But falling ants aside, the apparatus is set up so that the ants are forced to get back home...
- 01:16
...with the transported leaves, from a different path... without pheromones.
- 01:20
So... can they do it?
- 01:22
The graph shows that the ants did get the leaves back to their home, so since we know
- 01:26
that the leaves didn't transport themselves,
- 01:28
the ants must have figured out how to get back.
- 01:31
We already know our answer.
- 01:33
Option A says that the purpose of the experiment is to determine if ants can learn to return
- 01:38
to their nest by a different route.
- 01:41
And what do you know? We not only figured out that yes, the experiment was set up to
- 01:45
see if the ants can return...
- 01:47
...but we also figured out that they can get back.
- 01:50
Our answer is A.
- 01:51
What a touching homecoming. Maybe he'll get a parade.
