5
Q
Universal name
A
It allow biologists to identify and record previously unrecorded organisms and avoid repetition and confusion.

9
Q
Taxonomists look at:
A
- Homologous structures (very similar structure but may look different organisms)
- Analogous structures (different organisms that look similar, have similar functions but do not develop in the same way)
