Unit 10 Arthropoda Quiz

Phylum Arthropoda is a diverse group of invertebrates that includes trilobites, spiders, crabs, and insects. While trilobites belong to the subphylum Trilobita, spiders belong to Chelicerata, crabs to Crustacea, and insects to Hexapoda.

The correct class for spiders in the phylum Arthropoda is Arachnida, which includes spiders, scorpions, ticks, and mites. Insects belong to the class Insecta, crustaceans belong to the class Crustacea, and millipedes belong to the class Diplopoda.

Ticks belong to the Class Arachnida within the phylum Arthropoda, as they are arachnids and not insects (Class Insecta), crustaceans (Class Crustacea), or myriapods (Class Myriapoda).

The horseshoe crab belongs to the Class Merostomata within the phylum Arthropoda, and not in the classes Insecta, Arachnida, or Crustacea.

The correct subphylum for Phylum Arthropoda represented by goose barnacle is Crustacea. Crustacea includes common aquatic animals such as crabs, lobsters, shrimp, and barnacles.

Shrimp belongs to the Subphylum Crustacea within the Phylum Arthropoda. This subphylum includes various crustaceans such as shrimp, crabs, lobsters, and barnacles.

Crayfish belong to the Subphylum Crustacea within the Phylum Arthropoda due to their characteristics and evolutionary history. Subphylum Chelicerata includes spiders and scorpions, Subphylum Myriapoda includes millipedes and centipedes, and Subphylum Hexapoda includes insects.

Pill bugs or roly-polys belong to the subphylum Crustacea within the phylum Arthropoda. Subphylum Chelicerata, Subphylum Myriapoda, and Subphylum Hexapoda are other subphyla within the phylum Arthropoda that do not include pill bugs or roly-polys.

The centipede belongs to the Class Chilopoda within the phylum Arthropoda. While insects belong to Class Insecta, spiders belong to Class Arachnida, and crustaceans belong to Class Crustacea.

The correct answer is Class Diplopoda because millipedes belong to this class within the phylum Arthropoda. They are characterized by having two pairs of jointed legs on most body segments.

Insects, which belong to Class Insecta, are characterized by having six legs, while spiders and scorpions fall under Class Arachnida, crabs and lobsters under Class Crustacea, and millipedes under Class Diplopoda.

The correct common name for the horseshoe crab is Limulus. While the other options may sound plausible, they are not the correct common name for this unique marine creature.

Crawfish are freshwater crustaceans that are commonly referred to as Cambrus. While they share similarities with lobsters and shrimp, they are distinct in their own right.

The correct common name for the honey bee is Apis. While Melitta is a genus of bee in the family Melittidae, Bombus refers to bumblebees in the genus Bombus, and Halictus are sweat bees in the genus Halictus.

The Romalea grasshopper is commonly known simply as Romalea, not as Caelifera, Acrididae, or Orthoptera.
