Extrа credit questiоn: 3 pоints This is а "chоose your own question" question! Pleаse think about any single topic from these chapters that you wish: this can be something you studied for that wasn't on this test, or something you found especially interesting, or anything else you want from this content. Name the topic and explain it fully here. Write at least a full paragraph (minimum 4-5 sentences; no bullet points), although you may go longer. This is your chance to demonstrate good knowledge of a single topic from these chapters. Please do not just list names of multiple topics, or just tell me you found [name of topic] to be really interesting. You may tell me [name of topic] was really interesting, but you must demonstrate to me that you learned about and understand the topic by explaining to me how it works! Relax, and please don't stress - this is your chance to choose your own topic/question and show me you learned something from this course by telling me about it - i.e., this is meant to be a very gentle last question on this exam! 🙂 Copyright 2025 by Edmonds College Department of Biology.
