- Why does a mouse embryo develop faster than a human embryo, for example?What would happen if one cell was removed or damaged at the 2-cell stage of sea urchin embryo development? What about if one cell was removed at the 4-cell stage? At the 8-cell stage? How about if two cells were separated after the first cleavage and allowed to develop on their own?What is your opinion of the status of an 8-celled human embryo? Why?
- Which of the following best describes the concept of cell differentiation during the development of a multicellular organism? A. During development, all of the genes in the embryo's cells are expressed at first, but fewer and fewer are expressed as time proceeds. B. During development, different sets of genes are deleted from different cell types so that at the end of development, each cell has only the genes it needs. C. During development, different cells become specialized to have different phenotypes even though they all originated from the same cell. ..Cell differentiation occurs through _______________, whereas morphogenesis involves _______________. (a) pattern formation; cell determination (b) cell division; cell expansion (c) cell expansion; pattern formation (d) cell determination; cell division (e) cell determination; pattern formationIn cleavage states what is blastomeres, 2-cell stage, 4-cell stage, and 8-cell stage.
