Answer 11

subphylum of marine invertebrates that includes soft corals, anemones, and stony corals.

Question 12

Answer 12

• Kingdom of microscopic eukaryotic organisms (everything happens within a single cell membrane; more complex than animal cells)

Comb rows

Answer 22

Locomotion organs of ctenophores (comb jellies); made up of a series of transverse plates of large cilia fused at the base, called combs. The cilia beat and it strokes towards the statocyst, so the animal moves oral end first
