disadvantages of cephalization


disadvantages of cephalization

Full Description


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. Centralization evaluation As mentioned if more key decisions are made by top managers of an organization, structure is more centralized. Cephalization evolved several times within the animal kingdom, suggesting that it offers certain inherent advantages. advantages and disadvantages hence. 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 … Cephalization in the development of a functional “head” end of an organism. 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. 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 … *Response times vary by subject and question complexity. 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 … These differences … What are disadvantage of cephalization? What are the possible advantages and disadvantages in the evolutionary trend toward cephalization of the nervous system? Compare and contrast the amphibian and reptiles breathing mechanism. check_circle Expert Answer. When diversity is the lessened in the animal kingdom the overall structure begins to break down and the great, and even if there are … ; Primitive or simple -> similar to chordate ancestors that gave rise to vertebrates. 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. If we consider R&D as an organization we can allocate all features … Lancets (Amphixous)Label the four chordate characteristics on … A major disadvantage in bilateral symmetry is a consequence of an advantage of bilateral symmetry, cephalization. What are the possible advantages and disadvantages in the evolutionary trend toward cephalization of the nervous system? Q: Remaining Time: 43 minutes, 49 seconds. Several things results from this developmental step. Median response time is 34 minutes and may be longer for new subjects. 4. Maintain all four key characteristics throughout all life stages. Cephalization is a characteristic feature of the Bilateria, a large group containing the majority of animal phyla. Question. Check out a sample Q&A here. 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 See Answer. Ex. 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). First, is the concept of polarity. What are disadvantage of cephalization? Want to see the step-by-step answer?
