Information about the four organisms can be found on the Internet. Use credible websites to find answers to the questions you developed in part A. Based on this data, draw your own dichotomous key.



Based on the key you created, do you think some of the organisms are more closely related than others? Explain your answer.







Part 1 was this:A dichotomous key works on the principle of asking yes-or-no questions about the organism. To identify it, the answers for that organism are then compared to existing organisms to identify it. Prepare a list of four to five questions about each of the organisms listed below to help you create your own key. For each question, make sure the answer isn’t the same for all four organisms. For example, Does the organism have cells? would be an inappropriate question, because all the organisms have cells.




brewer’s yeast (Saccharomyces cerevisiae)



E. coli ba

Answer:

This may not exactly align with your answer but here's the key and I wrote for Part E:

Explanation:

Part E: Yes, I think that there are some closely related species of organisms that cannot be identified with a dichotomous key. Dichotomous key is used to classify objects or organisms based on its physical characteristics. Because of that limitation, there are species that may be related according to the dichotomous key but are in fact not or its relation is very minimal whereas there are organisms that may seem unrelated based on their physical characteristics but are actually from the same ancestors.
