Final answer:

Biramous appendages are two-branched while uniramous appendages are one-branched. Crustaceans and trilobites have biramous appendages, while myriapods and hexapods have uniramous appendages.

Step-by-step explanation:

In arthropods, biramous appendages refer to those that are "two-branched," while uniramous appendages are "one-branched." Biramous appendages are characteristic of crustaceans, such as crayfish, and trilobites. On the other hand, uniramous appendages are seen in myriapods, including centipedes and millipedes, as well as hexapods, which include insects. These terms describe the structure of the legs and their branching pattern.
