1 Brian Opp Biology 103 Class Data Report Seth Burdick In Biology 103 lab, we treated seeds with different concentrations of salt/other solutions and allowed them to germinate. The duration of the lab lasting one week and we recorded the class data accordingly. In my group, we used black-eye peas for a seed and Miracle Grow for a solution. As a group, we hypothesized that the Miracle Grow will increase the rate of growth and aid the black-eye peas. Immediately, we gathered four cups of solutions labeled 0%, 1%, 4%, and 10%. To make a 10% solution, we added 10 grams of NaCl (table salt) to the beaker and then added RO water to the 100ml mark. We poured 50ml of this solution in the 10% cup. We were left with 50ml of a 10% solution in the beaker. From there, we calculated the volume in ml of RO water

Unformatted text preview: to make a 4% solution. We were left with 25ml of the 4% solution, we calculated the volume of water needed to make a 1% solution. We came up with a final volume of 100ml and 75ml needed to make a 1% solution. We finally poured 50ml RO water into the 0% cup and obtained 50 seeds to germinate. We placed the seeds on germination paper and in sandwich bags and allowed them to grow for a week. 2 In conclusion, I was impressed by how the Miracle Grow affected germination. The Miracle Grow also made a significant change in the sweet pod experiment. All of the Black Eyed peas germinated in 0% and 4% concentrations, which backed my group’s hypothesis. I believe these seeds would be considered semi-tolerant to the solute. No seeds germinated at 1% and only four germinated at 10%....

    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.
