question 7
what connects all animals in phylum porifera?
o the swim
o they are animals
o they can eat a variety of food
o they have pores

Explanation:

Phylum Porifera (sponges) are defined by the presence of pores (ostia) for water flow, which is their key unifying feature. The other options are either incorrect (they do not swim) or too general (being animals or eating varied food applies to many other animal groups).

Answer:

They have pores
