Question

the classification levels of a human are listed below from largest to smallest.
eukarya
animalia
chordata
mammalia
primates
hominidae
homo
sapiens

which level of biological classification do mammalia and hominidae represent, respectively?
○ class and family
○ order and class
○ family and species
○ species and kingdom

Explanation:

To determine the classification levels of Mammalia and Hominidae, we recall the biological classification hierarchy (from largest to smallest): Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.

• Mammalia: In the given list, after Phylum (Chordata), the next level is Class. Mammalia is a class (e.g., all mammals belong to Class Mammalia).
• Hominidae: After Order (Primates), the next level is Family. Hominidae is a family (e.g., great apes including humans are in Hominidae).

Now we analyze the options:

• "class and family": Matches our analysis (Mammalia is class, Hominidae is family).
• "order and class": Incorrect (Mammalia is not order, Hominidae is not class).
• "family and species": Incorrect (Mammalia is not family, Hominidae is not species).
• "species and kingdom": Incorrect (Mammalia is not species, Hominidae is not kingdom).

Answer:

A. class and family
