Answer 1

1. The statement that best shows how scientists demonstrated that spontaneous generation is incorrect is:
   Louis Pasteur conducted an experiment on the growth of microbes in meat broth.

2. The statement that is true about both unicellular and multicellular organisms is:
   Both have DNA.

3. To provide the strongest support for the argument that viruses are not alive, the student should cite:
   All living things are made of cells.
   (Additionally, it’s relevant to note that viruses do not possess cellular structure, further supporting the argument.)
