Select the correct answer.Read this summary of a scientific theory:Cells are the most basic structural and functional units of life. All living organisms are made up of one or more cells. All cells that are alive in the world today came from pre-existing cells.Which of the following would require this theory to be modified? A. 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.

Cells are the most basic building block of life, and they are living things themselves. Evaluate what this means each cell is able to do, and the implications this has for both unicellular and multicellular organisms. Remember MRS GREN in your answer.
