archaea is false?

Suppose that one of Pasteur's swan neck flasks had broken, such that the neck came off. What would be the likely result?    Maggots would have appeared on the meat  The broth would have remained sterile  Bacteria would not have been isolated in pure culture  The animalcules would have escaped  The liquid would have become contaminated    You have a mixture of bacteria, archaea, fungi, protists, and algae. Which of the following would be most definitive in determining which of these cells are archaea?    Size in a bright field microscope  Structure in a scanning electron microscope  Fluorescence in situ hybridization  Super resolution microscopy Simple staining

One organism found in a termite’s gut is Mixotrichia paradoxa. This strange creature looks like a single-celled swimming ciliate under low magnification. However, the electron microscope reveals that it contains spherical bacteria rather than mitochondria and has on its surface, rather than cilia, hundreads and thousands of spirilla and bacilla bacteria. You are the scientists who first observed this organism. How would you describe this organism- single-celled? Aggregate? Colony? Multicellular? Can the structure of this organism give you any insight into the evolution of eukaryotic cells? (Hint: the endosymbiosis hypothesis)
