Exaptation
Explanation:
In this example, the lateral extensions that developed were meant for thermoregulation.
But these became sufficiently large to support gliding through the air and later on were used for flight.
Thus the structure assumed a function for which it was not meant and its original function shifted to a completely different dimension giving rise to modern insect wings. So we can say that this is an example of Exaptation.
Controlled burning? I think that's right.
1. “Research the problem” matches with “use reliable sources, talk to experts and take notes”
2. “Organize data” matches with “create charts or graphs to display the results”
3. “Design an experiment” matches with “set up a procedure for testing your ideas; including variables and controls”
4. “Hypothesis” matches with “must be testable and falsifiable”
5. “Choose a problem” matches with “Come up with a question that can be answered”
It would be Carbon Dioxide.
