Biology 20 IB: Make a Mesocosm in a Bottle Observations/Analysis October 23, 2018 Carrots have not yet started sprouting October 27, 2018 Carrots are starting to sprout Some green is visible Less than 1 centimetre tall November 3, 2018 Carrots have sprouted Approximately 6 centimetres tall November 10, 2018 Approximately 7 centimetres tall November 29, 2018 Approximately 9 centimetres tall December 15, 2018 Approximately 10 centimetres tall January 6, 2019 Approximately 12 centimetres tall Conclusion and Evaluation One of the errors throughout the experiment that could have affected the results is that the temperature of the environment surrounding the mesocosm was not completely constant, although there was not a huge difference, there were differences within a few degrees celsius. A way to reduce the impact of this error on the experiment is to carefully monitor the temperature inside the house by checking the temperature twice a day, once in the morning

    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.
