Question
Chapter 30.2, Problem 3MI
Summary Introduction
To determine: The condition in which viruses might choose lysogeny rather than lysis and the effect of this on carbon flow.
Introduction: In nature, viruses are categorized on the basis of their life cycles as lysogenic and lytic viruses. Lysogenic virus uses the machinery of the host cell and incorporates its DNA fragment into the cell without degrading the cell. However, the lytic virus kills the host after producing multiple copies of viruses to spread to the next organism. The process of lysogenic conversion means that the viral genome is combined with the genome of bacteria resulting in new properties shown by the bacteria.

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…
Bacteria in the digestive systems of animals that help to break down the animals’ food, and in return receive a sheltered habitat and food. This is an example of mutualism.
True
False
Under what conditions might bacteria want to coordinate (via quorum sensing) to increase their reproductive rate?

(Many antibiotics are excreted in their active form.) The influx of antibiotics into the environment is a concern because the presence of these compounds in the environment selects for antibiotic resistance. As pollutants, antibiotics can also have ecological effects. Describe some of the ecological roles of bacteria, and explain why disruption of these roles by antibiotic pollution would have a negative impact.arrow_forward
