Scientific observations show that microscopic organisms living in the deep ocean are not made up of cells. B. A survey finds that a majority of people believe viruses carry out the basic processes of life. C. The DNA of unicellular and multi-cellular organisms is shown to have many fundamental similarities. D. A prominent scientist says she feels strongly that one day the theory will be challenged by life on other planets.
