Question

which question is most likely to be found in a dichotomous key for identifying a tree by its leaves?
○ what is the shape of the tree’s leaves?
○ what type of birds prefer nesting in the tree?
○ are the leaf bases attached opposite to each other on the branch?
○ are the leaves shaped in a way that slows the evaporation of water?

Explanation:

A dichotomous key uses yes - no or two - choice questions for identification. The question “Are the leaf bases attached opposite to each other on the branch?” is a two - choice (yes/no) question about a leaf characteristic relevant to tree identification. The first option is an open - ended question about shape, not dichotomous. The second option is about birds, not leaf characteristics. The fourth option is about a functional aspect of leaves, not a simple identification - related characteristic.

Answer:

C. Are the leaf bases attached opposite to each other on the branch?
