What do you already know about somitogenesis? What other information is related to the question?
· The mesoderm gives rise to somitomeres, which give rise to somites.
· The timing of somitogenesis overlaps that of neurulatiom. The first somites appear in the 3nd week after fertilization.
Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
· Since somitogenesis occurs in the 3rd week after fertilization, January 3 and 7 are too early, and January 31 is too late.
· January 17 does coincide with the 3rd week of the pregnancy in this example.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use somitogenesis in a new situation. If you got an incorrect answer, did you remember that somitogenesis occurs in the 3rd week of a human pregnancy, or that the pregnancy in this example was intiated on January 1?
