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.

Research an interesting example of mutualism, and present your findings in a post. The goal here is to provide examples beyond what is presented in lecture and/or your textbook. These can be animal-animal, animal-fungal, plant-fungal, plant-animal, bacteria-animal....the sky is the limit! For this particular forum, you'll be able to see other classmates postings even before you post your own. This is so you can present an example that's different from what's already been discussed.
Remember that mutualistic interactions are associations that benefit both parties -- so your response should clearly indicate the role each partner plays.
Let us know where these organisms are found, what kind of habitat they live in, and any other interesting , pertinent information.
Also, please comment on how natural selection likely played a role in the development of your example. You can use your imagination a bit here -- I'd just like to see you connect the ideas.

This is a good example of natural selection; only the most fit (i.e., those with mutations conferring resistance, survive to reproduce and fill the niche with resistance organisms).

Converts atmospheric nitrogen to organic nitrogen. D. Composed of many species of bacteria.arrow_forwardExample: Three birds loved to eat beetles especially the green (female) and the brown (male). But their favorites are the green beetles. Generations later, green beetles have been selected and brown beetles have increased in number.- What do you think will happen if a disease was introduced and invaded the species living in an ecosystem?This is not aimed at the example, but you may use it as reference, thanks!arrow_forwardIdentify which of the following statements is a lie? Select one: a. Bacterial biofilms due to quorum sensing can be found on medical equipment and implants such as hip or knee replacements or heart pacemakers. b. Quorum sensing uses autoinducers as signaling molecules. Autoinducers are signaling molecules secreted by bacteria to communicate only with the same species of bacteria. c. The first evidence of bacterial communication was observed in a bacterium that has a symbiotic relationship with Hawaiian bobtail squid.arrow_forward

Temperatures at these vents can reach well over 100 degrees Celsius. Both organisms obtain energy from hydrogen but Methanopyrus kandleri grows best at 98 degrees Celsius while Pyrolobus fumarij prefers to reproduce at temperatures above 100 degrees Celsius. These bacteria provide the base of a food web at the bottom of the ocean floor. What questions could a student ask in order to investigate this difference between the bacteria? A. What kind of heat tolerance do other nearby organisms have? B. Does the Methanopyrus kandleri live farther away from the vent than the Pyrolobus fumarij? C. Does Methanopyrus kandleri have a thicker cell wall than Pyrolobus fumarij? D. Is one organism better adapted to the environment than the other?arrow_forward
