Chapter I Introduction I. Background of the Study One of the researchers was researching for a topic for an investigatory project concerning animals. The researcher came across with planarians having them tested on the effects on their skin regeneration when Carica Papaya and Allum Sativum are applied particularly on Roundworms (Caenorhabditis elegans). The researchers first thought of having planarians as the subjects of the study, but one of them proposed to change it because they would be having problems concerning the shape of planarians which appears that there are many variations. Therefore it was agreed upon to have roundworms instead of having planarians in general. According to: http://www.exploratorium.edu/imaging_station/research/planaria/story_planaria.pd f planarians have become the subject of interest of some scientists just like Hunt Morgan, the researcher who brought fruit fly genetics, began his study on the regeneration of planarians. The subject drew his interest because it formed a problem in a theory of inheritance put forth by German biologist August Weissman. Weissman’s idea, known as the germ plasm theory , postulated that each individual cell inherits only what material it needs to become a certain kind of cell. In other words, skin cells would contain only the material for skin cells, and so on. If this were true, Morgan argued, then regeneration

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
