Here's an unshmoopy question you may find on the ACT Science exam...
- 00:09
Time to pause and review.
- 00:10
No, not your sister's diary. This passage, s'il vous plait.
- 00:23
Which of the following pieces of evidence strongly supports the idea that plant patterning
- 00:27
is caused by mechanical stress?
Full Transcript
- 00:30
And here are the potential answers...
- 00:37
This problem is asking us to find some solid evidence to support the idea of mechanical
- 00:42
stress causing patterning.
- 00:44
Well, we could read the passage yet again...or, we can use our awesome deducing skills to
- 00:48
figure out the answer by just looking at the choices.
- 00:52
So how do we deduce the answer?
- 00:54
Well, we're looking for evidence. Evidence means that it's something that we have observed.
- 00:59
Option A is true, but it doesn't provide us with how we have
- 01:02
observed it, or how it affects patterning.
- 01:04
Same with Option C. We know that auxin causes plants to grow,
- 01:07
but it doesn't provide evidence of mechanical stress causing patterning.
- 01:11
Option B. Those adorable patterns on raccoons do not have anything to do with PLANT pattering.
- 01:17
That leaves us with D.
- 01:18
"Scientists can injure a plant, and the plant patterning responds to this action
- 01:22
by taking on a pattern dependent on the size of the injury."
- 01:27
Sounds like pretty solid evidence to us.
- 01:29
Thorough, and it explains the effect of observation on patterning.
- 01:34
So D is the best answer.
