In a centralized organization structure , the centralized authority may have a better perspective on the big picture of the organization and how the subunits of the organization fit … Compare and contrast the amphibian and reptiles breathing mechanism. Centralization evaluation As mentioned if more key decisions are made by top managers of an organization, structure is more centralized. In particular, with the evolution of cephalization, the anterior end of the animal became most likely to first encounter food, predators, and other important features of the external environment. A major disadvantage in bilateral symmetry is a consequence of an advantage of bilateral symmetry, cephalization. First, is the concept of polarity. Cephalization evolved several times within the animal kingdom, suggesting that it offers certain inherent advantages. 4. ; Primitive or simple -> similar to chordate ancestors that gave rise to vertebrates. If we consider R&D as an organization we can allocate all features … Maintain all four key characteristics throughout all life stages. advantages and disadvantages hence. What are disadvantage of cephalization? Cephalization in the development of a functional “head” end of an organism. Cephalization definition is - a tendency in the evolution of organisms to concentrate the sensory and neural organs in an anterior head. Step-by-step solution: Chapter: CH1 CH2 CH3 CH4 CH5 CH6 CH7 CH8 CH9 CH10 CH11 CH12 CH13 CH14 CH15 CH16 CH17 CH18 CH19 CH20 CH21 CH22 CH23 CH24 CH25 CH26 CH27 CH28 CH29 … The organism now demonstrates significant differences along the length of its body, so that a head end can now be distinguished from a tail end. Q: Remaining Time: 43 minutes, 49 seconds. Want to see the step-by-step answer? Several things results from this developmental step. When diversity is the lessened in the animal kingdom the overall structure begins to break down and the great, and even if there are … Cephalization is a characteristic feature of the Bilateria, a large group containing the majority of animal phyla. What are the possible advantages and disadvantages in the evolutionary trend toward cephalization of the nervous system? Question. Advantages and Disadvantages of Centralization Under certain conditions a centralized organizational structure can be advantageous. ; The pharynx has ~100 pharyngeal slits which are used in feeding (filter food particles out of the water). *Response times vary by subject and question complexity. These have the ability to move, using muscles, and a body plan with a front end that encounters stimuli first as the animal moves forwards, and accordingly has evolved to contain many of the body's sense organs, able to … Check out a sample Q&A here. Lancets (Amphixous)Label the four chordate characteristics on … These differences … check_circle Expert Answer. See Answer. Ex. Median response time is 34 minutes and may be longer for new subjects. What are the possible advantages and disadvantages in the evolutionary trend toward cephalization of the nervous system? What are disadvantage of cephalization? Correct answers: 2 question: List the advantage and disadvantage of: a. coral reefs b. cephalization c. coelom d. ecdysis e. multiple host life cycle f. proglottids g. multiple mouths h. incomplete digestive tract i. ventral nerves j. parthenogenesis k. statoblasts l. ontogenetic torsion m. hydrostatic skeleton This shape of management has some advantages and also several disadvantages. The biggest disadvantage of bilateral symmetry is the fact that there is so little diversity in the structure, which makes it a big problem as far as evolution and adaptability is concerned.
