ANALOGY OF SQUIRREL ISLAND

An isolated chain of islands known as the squirrel islands exists in the Pacific Ocean.The island group consists of three separate islands named A, B, and C.The three islands are each 5 miles apart.See diagram below.

The islands support various wildlife including a population of 10,000 squirrels per island.Although the island group is isolated, there is a bit of mixing of squirrels between islands.Occasionally a very ambitious squirrel will swim from one island to another in search of a better life.It is rare—but it does happen.

One day, on island B, a squirrel was born that was named Chip by his parents. Chip looked like all the other squirrels on the island on the surface but was actually a mutant.

CHIPS – the mutantsNORMALS- the non mutants

When Chip was just a one-celled embryo, one base a “T” in his DNA was changed to a “C”.The change happened in a gene that coded for an electron transport chain enzyme.This mutation is carried in all cells of his body.The mutation has both positive and negative effects on chip.

— On the down side, Chip still makes the ETC enzyme but it has a slightly different shape and doesn’t work as well.This means that his ETC won’t generate a hydrogen ion gradient as quickly as the normal squirrels.He has to consume more glucose than other squirrels in order to make the same amount of ATP.The result is that Chip and all of his descendants when he has them will have to eat 5 nuts a day in order to survive, while the normal squirrels have to only consume 4 nuts a day to survive.

choose from among the beneficial organisms below.

• Please choose one of the following beneficial microbes to write about.

  Bacillus polymyxa Brettanomyces bruxellensis Geobacter metallireducens Ideonella sakaiensis Lactobacillus gasseri Penicillium camemberti Pseudomonas putida Saccharomyces cerevisiae Shewanella oneidensis Sinorhizobium meliloti Streptomyces griseus . Synechococcus elongatus

• You must discuss your chosen organism to tell us what type of microbe it is, what helpful beneficial actions it performs and which subfield of microbiology it is involved in. You must discuss only the helpful, beneficial, positive aspects of your chosen organism for your entire main discussion. This should be well-written, in your own words, paraphrasing from only credible academic sources. You may not directly quote from your sources. You must also cite your credible academic reference sources in text and provide full end ref information in APA format. The initial post must be at least 300-400 words . Again, you should provide student original writing and cite your source for this post and provide full end ref information in APA format.
  • You may never use Wikipedia or any other Open Source to support your work! All assignments using these will earn zero score.
  • You must paraphrase from all sources as direct quotation is not acceptable in science writing.

Choose one article from a primary scientific literature source that uses a microbe as a model organism/system and write a comprehensive summary of the study that answers the following questions:

Choose one article from a primary scientific literature source that uses a microbe as a model organism/system.
NOTE: Many free articles may be obtained from http://www.pubmed.gov

Write a summary of the study that includes:

1. Why did the scientists perform the study (i.e., description of background)?
2. What was the hypothesis (or hypotheses) under investigation?
3. What were the major results and did they support or negate the hypothesis? Which key techniques were used to achieve these results?
4. Why are the results significant and do they point to further/future studies? In other words, why does this article matter and what should or could be done next?
5. Why did you choose this particular article to review? Was it interesting, informative, clearly written, or none of the above?

Compose your review in APA format and include:

• A title page
• Answers to the questions above in paragraph format (2 or more pages)
• A reference page with the reference for your article and any other sources used in your review.
