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 O Both of the cells will die O Both cells develop into complete and normal embryos that are somewhat smaller O One cell develops into a normal though smaller embryo the other dies O One cell develops into half an embryo the other develops into the other half of the embryo O One cell develops into a defective embryo and the other dies QUESTION 26 Why are viruses not considered to be organisms and not described as being alive O Virions are unable to reproduce by themselves O Virions are not able to metabolize by themselves O Virions are not able to synthesize DNA by themselves O Virions are not able to assemble spontaneously O Virions are unable to reproduce by themselves to metabolize by themselves or to assemble spontaneously
