How does a dichotomous key help you identify unknown specimens based on their traits? Answer with details about the format and s
Aneli [31]

Considering you need to identify an organism. So, on the top of they key is animal with options: (a) with red blood cells and (b) no red blood cells. The option you will select is no red blood cells and under option b, you’re given two choices again: (a) hard bodies and (b) soft bodies.
