- How do I create a bar graph using the hardy Weinberg data provided but in the bar graph format on the right ?Design a simple, manipulative experiment to test the hypothesis that synthetic fertilizers in the environment influence the population density of the salamander, Ambystoma tigrinum. Your experiment can have no fewer than two treatments and no more than four. State your hypothesis. Briefly describe your experiment. Address the following: Is it a field or lab experiment? What are the treatments, how are they set up, and what differentiates them? How many replicates of each treatment will there be? What are the standardized conditions of your experiment? C. Identify the independent variable, including units, in your experiment. D. Identify the dependent variable, including units, in your experiment. E. Identify at least one control treatment and explain its specific role in the experiment.Why is variation beneficial to the species but not necessary for the individual?
