human development? What do the two have in common?
Which of the following is true about Sea urchin blastula formation and fate map?
a) ectoderm that develops into the larval skin and neurons, is regularly produced by the
vegetal half of the embryo.
b) an1 layer generates cells that can enter either the ectodermal or endodermal organs of
the larva.
