PART 1 Find and read 2 different types of nutrition-related articles published on the Internet.

Article 1: This should be an article of interest to you which you find on a web site or link you have already explored in this class, or others with which you are familiar. It should include general information but should NOT be a research article although it may include explanation about some research as supporting evidence. The article should be more than just a paragraph or a blog. If using Google or another search engine, try to narrow the topic when you conduct your search so it is specifici.e. type 2 diabetes and weight loss; the benefits of 7 to 9 servings of fruits and vegetables; breastfeeding and decreased risk of allergies; depression and Vit.

You need to find a Full Text Article and it needs to explain research (an experiment or a summary of experiments that follow the scientific method). Scan the entire article to review the parts of research (may include: abstract, introduction, methods or design, data analysis, results, discussion, limitations, conclusion).You need to read at least the Abstract, the Introduction, the Results and Discussion and the Conclusion to complete this assignment.

Instead of thinking that you have to complete the entire dissertation, plan writing separate chapters, or to research different aspects of your topic. By doing so, you’ll make it easier for yourself to stay on track, stick to the schedule, and overcome any possible difficulties. Develop a plan with all the small tasks that will eventually make up your dissertation, and you won’t even notice how easy the entire process is.

4. Start Writing

Even if you don’t know where to start, just start writing. This trick is a go-to of many professional thesis writers.

Whether you feel the most comfortable with a literature review or an introduction at this point doesn’t matter. Either way, you know that the appetite comes during the meal, and inspiration works the same way. 

5. Focus on Self-Care

Taking care of yourself is always important, but it is also of critical value when you’re working on your dissertation. If you’re exhausted both physically and emotionally, no good will come from your attempts to complete a dissertation. On the contrary, getting enough sleep at night, eating healthy foods, , and keeping your muscles toned will only improve your ability to conduct research and write a complex text. Be sure to develop a routine that allows for both work and relaxation.

a) Is child B the son of the father?  Explain your reasoning in terms of the combined paternity index.

b) If A and B had children together what would be their possible genotypes for the genetic locus studied here?
