Question

PLS HELP IVE BEEN STUCK ON THIS FOR 2 DAYS AND I HAVE TO TURN IT IN SOON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Part A: 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.

Part B: 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.
