As stated in the last module, this week you will exchange your draft with a partner so they can review it with the rubric. The goal of this exchange is to help mold and rework your draft for submission by Saturday. Because this is a quick turnaround, please make sure you complete the review of your peer’s paper by Thursday so that they will have time to make any changes prior to submission. Additionally, posting your draft prior to Tuesday is strongly encouraged as this will allow additional time for your peer to review your draft. Remember, in total, your research paper needs to be written and formatted using the APA style guide and should include 5-6 pages of text. Your page requirement does not include the cover page, abstract, or reference page. Your research paper should also include a minimum of 3-4 reputable sources. Apa research paper on prymids

Find or create an image (for this activity, a smaller starting image will produce higher quality results in a shorter amount of time). 2. Using the Python documentation as a guide, create a program that loads the image, filters three copies of it, and saves the result. Note: You will need to create the three filters using the filter() method. • Include multiple filters on at least two of your variants. One of your variants must apply a single filter multiple times with the use of a loop. For example, the top right image above uses a loop to blur the image 2 times (what if we did it 100 times?).
