To which of the 5 clades do these organisms belong?

What is the difference between Systematic Biology and Taxonomy?

In the binomial naming system, scientific names are written in italics, with the first word capitalized and the second not capitalized. The scientific name of a type of fungus beetle is therefore written as Gelae donut (pronounced “jelly donut,” seriously!). Which level of the classification system does each word of that scientific name represent? (Note: this is NOT a multiple choice question…) Gelae = donut =

Organisms A, B, and C are all in the same family.  Organisms B and C are in the same genus. Given that information, select all the true statements about the relationships among these organisms. Group of answer choices organisms A, B, and C are in the same domain organisms A, B, and C are in the same phylum organisms A, B, and C are in the same order organism C is more related to A than to B organisms A, B, and C are in the same species organism B is more related to C than to A
