which question would be asked in a dichotomous key?\n○ how long are the insect’s antennae?\n○ are the insect’s antennae longer than its head?\n○ are the insect’s antennae long or short?\n○ how does the insect use its antennae?

Answer

Brief Explanations:

A dichotomous key uses questions with two mutually exclusive (yes/no or either/or) answers. "How long..." is open - ended (not dichotomous). "Are the insect’s antennae longer than its head?" is a yes/no question (dichotomous). "Are the insect’s antennae long or short?" has two options but is more of a choice between two descriptive terms, while a dichotomous key typically uses a yes/no format for clear binary classification. "How does the insect use its antennae?" is open - ended. So the question "Are the insect’s antennae longer than its head?" fits a dichotomous key.

Answer:

B. Are the insect's antennae longer than its head? (assuming the options are labeled A, B, C, D with the second option as B)
