Unformatted text preview: untreated blackworm had an average pulsation rate of 20.67 beats/ minute while both drug A and drug B reduced the pulsation rate to 18 beats/ minute and 12.7 beats/ minute respectively. Discussion The purpose of this experiment was to measure the metabolic rate. A simple organism with transparent skin that is easily diffusible in solutions was used. The pulsation rates were measured by visually counting the beats per minute. The data appropriately displayed the overall metabolic rate in the organism....

    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.

    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.
