MICROBIOLOGY EXAM 1 WITH COMPLETE SOLUTIONS 100% Characteristics of living systems were discussed in the book and lecture introductions. Which is NOT a characteristic of most, if not all, cellular life? - correct answer fermentation You have something in common with some of the bacteria. That is, some bacteria (and you) are heterotrophic. Because there are many kinds of metabolic options for bacteria, it is better to be more specific and call organisms that gain their energy from the oxida...
