Question

Which is an example of a structural adaptation?

A. the growth of a houseplant towards sunlight
B. seeds that sprout after a forest fire
C. dormancy of a plant during a drought
D. the wing-shaped seeds of a tree

Answer 1

First of all, we can simply find the answer, if we pay attention to what the question is asking. It's asking for a STRUCTURAL adaptation, which means the adaptation we search for needs to involve a change in structure.

Nor A, B or C represent a change in structure, but B does. It shows us a change in the structure of tree seeds, which has helped them during reproduction.

Hope it helped,
