1. From where are micromeres derived? Why are they smaller than macromeres? 2. In the early stages of amphibian development, what layer is involved in yolk digestion? What is the basis for the distinction between germ layers in gastrulation? 3. In amphibian gastrulation, are there any evidences of cephalization? Why or why not?

Discuss Concepts Developmental biologist Lewis Wolpert once observed that it is not birth, marriage or death, but gastrulation which is truly the most important time in your life. In what sense is he correct?
33. In words and/or a diagram, describe the molecular components of the developmental timing mechanism responsible for the formation of somites of the proper size and placement within the chick embryo. Make sure to include in your answer how the molecular components are coordinated by growth of the embryo to control somite formation: ? How How could this developmental timing mechanism be manipulated to produce longer somites could this developmental timing mechanism be manipulated to increase the rate of somite production ( ,?
Explain the developmental and functional similarities and differences between: 1. Avian yolk sacs and mammalian yolk sacs 2. Avian chorions and mammalian chorions 3. Avian allantois and mammalian allantois
14. Following fertilization, a zygote divides and soon becomes a 2 po multicellular embryo with many different cell types, as represented below. Which statement best explains this development? * Zygote Embryo Muscle cells Intestinal cells Liver cells Blood cells Nerve cell Cardiac cells Specialization occurs, resulting in the formation of a great variety of cell types Genes are inserted into the zygote to allow for the formation of different cell types The expression of genes responsible for the different cell types is controlled by the placenta The genetic information in the zygote is divided to produced a complete set for each cell type.
3. (a) What are the four processes that drive embryonic development? (b) What two processes drive morphogenesis in a developing embryo?
