Investigate about Down Syndrome and write an essay about it. The questions provided above are to motivate you to investigate about this topic; you do not need to answer them one by one. The essay must be at least five paragraphs long, and each paragraph must contain at least five sentences (you can write more than five paragraphs and more than five sentences per paragraph if you wish to do so). The content of your essay must be written entirely in your OWN words. Use in-text citations in parenthesis, APA style, if you paraphrase information from other authors. Paraphrasing is not copy-pasting or copying and changing a few words from other authors’ writings – it is writing it in your OWN words to explain the authors’ writings. Only when necessary you can quote, but these quotes do not count towards the last tally of the number of paragraphs and sentences required from your OWN writing. You must cite and list at least four references you used to investigate about this topic at the end of your essay (use APA style). You must submit your assignment using SafeAssign; your assignment will not be evaluated if it is not submitted through SafeAssign. This assignment can be submitted twice, and only the last submission
