Which level of biological classification is the lowest level that butterflies (invertebrates) and dogs (vertebrates) have in common?

A domain

b kingdom

c species

d family

The answer is Kingdom A

Ans.

The lowest level of biological classification that butterflies and dogs have in common is kingdom as they both belong to kingdom 'Animalia.' Organisms that belong to kingdom Animalia are muticellular, eukaryotic (have cells with true nucleus and membrane-enclosed organelles), and heterotrophic organisms (depend on other organisms for food).

As all these features are shared by both butterflies and dogs, thus, they both are grouped within kingdom Animalia. Thus, the correct answer is 'option b). kingdom.'
