For instance, you can select an article about medicine, invasive species, nature, conservation, genetic technology, ecology, or any other topic that is related to biology. One purpose of this assignment is to help you become aware of how biology is related to your everyday life.

Write a one to three (1-3) page paper in which you:

1. Summarize the article in one (1) or more paragraphs, using your own words. Be sure to identify the article using an in-text citation in the body of the paper, as well as a reference in the reference section. 
2. Explain how the article relates to this course. Identify which biological concepts from the course and / or text are relevant to the topic covered in the article. Citing the course text, discuss the ways in which this course does (or doesn’t) provide background information to help you understand the article and the larger issues surrounding it. 
3. Explain why the article caught your attention. Relate the article to your life and to issues that are important to you. Discuss how or if the scientific knowledge about the topic covered in the article affects you directly or indirectly.
4. Discuss your opinion on how research on this topic should be funded. State whether you think taxpayer monies should support research on this topic or whether such research in this area should be funded by the private sector. Rate the importance of research on this topic, relative to other areas of research. 

In addition to the target article, you should use at least one additional resource, such as your textbook or another article. You must have a reference section which contains an APA reference to your chosen article and all other sources. Additionally, you must provide in-text citations (in APA format) to your references in the body of the text. Integrate all sources into your paper using proper techniques of quoting, paraphrasing and summarizing, along with your in-text citations.

Your assignment must follow these formatting requirements:

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
