Cedar Crest Germination Success in Response to Soils Salt Concentration

Cedar Crest Germination Success in Response to Soils Salt Concentration Cedar Crest Germination Success in Response to Soils Salt Concentration I have a project assignment in Foundation of biology lap. All the questions on the file that I will put it here. I need someone good in biology and answers all the qu study_pool.docx Plant Project Lab Notebook Each figure should have an experimental hypothesis and null hypothesis listed. Here are the three figures to include in your notebook: Figure 1 Write-up 2020 Due: Thursday, November 26, 2020 During the course of the semester, you were asked to observe the growth properties of Arabidopsis sp. plants by observing the efficiency of germination at 14 and 21 days, and determining the rosette size at the time of inflorescence. The overall goal of the project was to determine whether the salt concentration in the soil with affect the growth of Arabidopsis plants. To carry out the experiment, plants were grown while changing the variable of the salinity (salt concentration) of the soil. Plants were either treated with water (Control), a low salt solution, or a high salt solution during the growth period. You will be creating three figures in your lab notebook. Each should have a figure legend underneath it with a 3-4 sentence description of what is in the figure and what the “take home message” is for that figure (i.e., did the salt have an impact on the results).. In this experiment, we were measuring the germination success at 14 days in response to the salt concentration in the soil. You should write out an experimental and a null hypothesis for this experiment. You will need to calculate the percent germination rate of the seeds (100 x number of germinated seeds/number of planted seeds). You should then graph the percent germinated seeds for the control, low salt, and high salt treatments. Create a figure with the three conditions on the xaxis, and “% germination” on the y-axis. Draw three bars to represent the percentages. Figure 2. In this experiment, we were measuring the germination success at 21 days in response to the salt concentration in the soil. You should write out an experimental and a null hypothesis for this experiment. You will need to calculate the percent germination rate of the seeds (100 x number of germinated seeds/number of planted seeds). You should then graph the percent germinated seeds fo r the control, low salt, and high salt treatments.Cedar Crest Germination Success in Response to Soils Salt Concentration Lab Report.

Draw three bars to represent the percentages. Figure 3. In this experiment, we were measuring the rosette size in response to the salt concentration in the soil. You should write out an experimental and a null hypothesis for this experiment. We have calculated the standard error of the mean for you using the formulas below, but you will need to calculate the mean size (average size) of the rosettes for each of the conditions. You should then graph the mean size (in mm) of the rosettes comparing the means and standard error (a measure of the variation in the data) for the control, low salt, and high salt treatments. Create a figure with the three conditions on the x-axis, and “Mean rosette size” on the y-axis. Draw three lines to represent the means. Then draw on the standard error bars around the top of the graph to show the amount of variation in the data. The standard error calculation is a + number (if your standard error was “2.5”, you should draw an error bar 2.5 units above and 2.5 units below the top of the bar that represents your mean).

In your lab notebook, please write a one- to-two paragraph summary of your results as the Conclusion of your notebook entry on the plant experiment. Be sure to compare the data shown in Figures 1, 2, and then discuss what the results in figure 3 suggest. Try to make a conclusion about the hypotheses that we tested. … Get a 10 % discount on an order above $ 100 Use the following coupon code : NURSING10
