By Movement Bacilli-use or "tail"Which of these statements is false? Microbiology is one of the largest and most complex of the biological sciences O Microbiology is a specialized area of biology that deals with tiny life forms that are not readily observed without magnification. The major groups of microbes included in this field of study are bacteria, viruses, fungi, protozoa, algae, and helminths. Every single microbiologist works in a lab.1. If microbial life had not evolved, would you be here today? Give one good reason why or why not and How does a microbial community differ from a microbial population?
- Chapter 9 L discusses some oxygen requirement, grouped. We're going to focus on those that do not necessarily need oxygen for survival. For this part: aerotolerance, categories under which most prokaryotic organisms can be 1. What oxygen requirement, or aerotolerance, categories allow for an organism to survive in the complete absence of oxygen? Please list those oxygen requirement/aerotolerance categories where an organism doesn't necessarily need oxygen for growth. 2. Oxygen is toxic to most organisms, even you! One reason we don't see the effects of this is because most organisms are able to produce enzymes to counteract this toxicity. This is called, "detoxifying reactive oxygen species (ROS)," as discussed in Chapter 9. In order to survive in the presence of oxygen (if it can), a prokaryotic organism must be able to undergo detoxification of reactive oxygen species. For each category you listed in 1), please provide: A. the enzymes that may be lacking/missing in order to detoxify…Describe the roles of microbes in: a. The formation of root nodules and The Rhizosphere c. The Ruminant Stomach d. The causes and consequences of algal blooms e. Life in deep sea vents (Tubeworms) f. Coral Reefs and Bleaching g.
