question 10 (1 point)
which of the following statements is true?
a genus does not always have species.
we never apply the term \concrete\ to concepts like genus and species.
sometimes the genus is more concrete, and sometimes its species are more concrete.

Explanation:

• For the first option: In biological classification, a genus is a taxonomic rank that contains one or more species. So a genus always has species, making this option false.
• For the second option: Genus and species are abstract taxonomic concepts, and the term "concrete" (referring to tangible, specific entities) is not applied to them. This aligns with biological and philosophical understandings of these taxonomic categories.
• For the third option: Genus is a more general category, and species are more specific (hence more concrete in terms of representing particular organisms). The genus is less concrete than its species, so this statement is false.

Answer:

B. We never apply the term "concrete" to concepts like genus and species.
