You are conducting an experiment by trying to reproduce the work performed in 1891 by Hans Driesch, a German embryologist. You are working with a fertilized sea urchin egg and allow it to complete the first cell division after fertilization. You then carefully separate the two cells of the embryo and allow their development to continue. Based on Driesch's experiment, which result below would you expect to happen?a) Both of the cells will die. b) Both cells develop into complete and normal embryos that are somewhat smaller. c) One cell develops into a normal, though smaller, embryo; the other dies. d) One cell develops into half an embryo; the other develops into the other half of the embrye) One cell develops into a defective embryo and the other dies.
