Rana Pipiens Vs. Procambarus Clarkii

Rana pipiens and Procambarus clarkii dont seem to have some(prenominal) in common since they are both parts of antithetic clades and more than importantly different phylum. Rana pipiens is a craniate and referable to the two stages of life it is part of the class Amphibia. Procambarus clarkii is an wishy-washy in the Arthropod class. In order to discover any similarities that big man of affairs exist between these two different organisms, scientists do relative anatomy studies. These studies help them discover if there might be any similarities between organisms that are part of different clades, groups, or phylum. In order to advance my knowledge of invertebrates and vertebrates we are conducting a comparative occupy between Rana pipiens and Procambarus clarkii. My hypothesis for this piece of work is that the Rana pipiens and Procambarus clarkii will both have closed circulatory systems. Also the Rana pipiens will have a truly well-defined reproductive system; I will be able to clearly identify it. The Procambarus clarkii will have a less-defined reproductive system; it wont be as easy to identify it. My study was conducted at a biology Lab at Northeastern Illinois University with my three lab partners. We straining the dissecting pans and preserved specimens from the university as well as pins to keep them in place.

We each employ our own dissecting kits during the dissections. We received dissection guides for both organisms that gave us step by step directions. When we dissected the Procambarus clarkii we first started with an orthogonal reflectivity then moved to the inward dissection. We first conservatively removed the cephalothorax and k eep ond the muscles underneath. After each d! etailed bill we began to remove the organs one by one to go on everything underneath until we observed the circulatory systems, digestive tracts, and reproductive system. During this dissection we apply the Bio 202-Crayfish Dissection Guide by F.R. Prete and K. Nuss from Northeastern Illinois University.
