Which of the following would be the lowest in cephalization? a. arthropods b. mammals C. mollusks D. cnidarians
The answer is D. Cnidarians
The correct answer is: D) Cnidaria. Cephalization is a process that describes the occurrence of a definite head possessing a well-developed mind, which controls the entire body of the organism. Vertebrates such as mammals are basically the most heady organisms as they include a highly developed head with a nervous system. Among invertebrates, some cephalic organisms include insects, spiders, mites (which come below arthropods). Cnidarians like sea anemones, jellyfish have weaker cephalization because they only contain a fundamental nervous system, but they are headless.
the answer is A. hope you bought a very good review
The answer is B. Cnidarians
They are cnidarians, the cnidarians of the phylum all have diploblastic animals and therefore exist in polyp type (stationary type) or medusa type (free-swimming type). Diploblastic animals have only two layers of cells, they have a mouth, but the physical division of head and trunk does not exist in this phylum. Hydra is a traditional example of cnidarians. While they have an anterior and posterior finish but no clearly demarcated cephalic construct and hence they would be the lowest in cephalization
My biggest answer might be A) Cnidarians
Redone is the least I believe
when organisms tend to cluster all of their major organs near the entrance to their body.
