In this item, we’re filling in two blanks about the structure of the scientific name in binomial nomenclature. The statement says: The scientific name of every organism consists of the _ name, which is listed first, and the _, which is listed second.

Option for 空白1: genus
- This option identifies the first component as the genus name. In binomial nomenclature, the first word is indeed the genus, and it is always listed first. Therefore, inserting genus for the first blank correctly describes the order of the two parts.
- Why this makes sense: The genus provides a broader classification group that contains one or more species. The phrase “listed first” aligns with how genus is conventionally placed before the species epithet in the scientific name. This option is consistent with the standard convention, so it is accurate for the first blank.

Option for 空白2: species
- This option designates the second component as species. The second part of the binomial name is the species epithet (often called the species name), which follows the genus. Thus, placing species in the second blank correctly completes the standard order.
- Why this makes sense: The species epithet identifies a particular species within the genus, and it is always the second word in a binomial name. This option correctly describes the second component, so it is accurate for the second blank.

Potential confusion you might watch out for:
- If someone hesitates and tries to swap the order (e.g., place species first), that would contradict the standard convention; this option helps reinforce the correct order by addressing the second blank.
- Some might wonder whether “species” should be capitalized or treated as a noun; here the focus is on position, and the convention is capitalizing the genus but not the species epithet in most formatting. The content of the option is correct regarding which term belongs in which position.

Overall, both options align with the established rule: the genus is the first component, and the species epithet is the second component in a scientific name.

The scientific name of every organism consists of two components: the name, which is listed first, and the , which is listed second.
