16. Species
17. Kingdom
18. Order
19. Species
20. Kingdom, Phylum, Class, Order
21. Mountain Lions and Domestic dogs. They are most related because they
have more taxa in common.
22. Kingdom, Phylum
23. Class Amphibia
24. Primates (order), Hominidea (family), Homo (genus)
25. Rana temporaria is most related to green frogs (Rana clamitans). I know
this because they share the same Genus, which means they also share the
same family, order, class, phylum, and kingdom.
