ve you more credit for 14. (This problem is s t into two different problems 14 and 15 to the graphs). One environmental factor that plants monitor is the duration of light. The length of an uninterrupted dark period is often extremely important in the kind of growth (vegetative as compared to flowering) Long-day (LD) plants require at least a certain day length before they begin to flower, whereas short-day (SD) plants require at most a certain day length before they begin to flower In the corn belt in the United States, sunrise and sunset define the length of the day. For example, here are the times of sunrise and sunset of the first day of each month in northern Iowa Sunrise Month Sunset 7:22 4:45 Feb 7:09 19 5:52 Mar 6:34 A 5:44 6:24 500 May 6:54 4:33 17:23 Jun Oul 4:35 17:33 Aug 4:58 714 6:32 Oct 5:56 5:43 Nov 6:29 4:35 Dec 7:02 a. Plot the sunrise and sunset times on the same graph You can do this either on the computer with Excel or by hand on graph paper. If you draw this by hand, make sure to scan your graph and then paste the image into the document that you will be submitting for grading. Please label your graph and axes properly: title below the graph (Figure 1. Give your own title here), x axis X title (in -hint: measured in what units?); y axis Y title (in? units). Typically, in science, graphs show the independent variable on the x-axis, and dependent variable on the y- axis. So, you will need to figure out which of these is the independent variable, and which is the dependent variable. The independent variable is the variable that is directly manipulated by a scientist during an experiment. The dependent variable is not directly manipulated by a scientist, and instead changes in response to a change in the independent variable.) b. Plot the duration of light per day and thc duration of dark pcr day on the same second graph (see (a) for graphing instructions)
