Question

(20 POINTS IF RIGHT) (i couldn't find science)

Answer 1

The correct answer is 4) A dichotomous key is complete when each organism stands alone.

The statement about a dichotomous key that is true is "A dichotomous key is complete when each organism stands alone."

Scientists have the need to correctly identify organisms, animals, plants, and objects. For that to happen, they have dichotomous keys.

These tools help them to identify and give a correct name that differentiates from other objects and organisms. So the most important thing about the dichotomous key is the fact that it identifies an organism, species or objects with its scientific name.
