Instructions

In a moment, we will return to our scenarios regarding water molecules and eventually Alzheimer's disease as well. Before we do that, you will complete this brief concept check to review your understanding of some of the language we're developing. You can attempt this quiz as many times as you wish (no time limit) and only your highest score will count. Feel free to open up another browser window so you can view earlier pages in this module or access our online textbook while you complete the quiz!
