which of the following statements describes crustaceans?
○ porous marine invertebrates who pull water through their soft bodies in order to obtain oxygen and nutrition
○ all aquatic vertebrate animals with gills that dont have appendages with digits
○ members of the arthropod phylum who have crusty, hard, outer shells
○ a type of segmented worm with two sets of two eyes, multiple antennae, and small appendages that aid in feeding and sensing

Explanation:

First Question (Organism Classification)

The taxonomic hierarchy (organism organization) from largest to smallest group is kingdom, phylum, class, order, family, genus, species. Other options have incorrect order (e.g., starting with small groups or jumbled hierarchy).

• Option 1: Describes sponges (porous marine invertebrates).
• Option 2: Describes fish (aquatic vertebrates with gills, no digit - appendages).
• Option 3: Crustaceans are arthropods (phylum Arthropoda) with hard outer shells (exoskeletons), so this matches.
• Option 4: Describes something like a type of worm (not crustaceans, which are arthropods, not worms).

Answer:

A. kingdom, phylum, class, order, family, genus, species
