Hi, my name is Mariah and I am a senior history major at Haverford. I am taking this course because although while in high school bio was always one of my favorite classes, I am not much of a science person. I think that this class will cover topics I have always been interested in, but in a more approachable and meaningful way. Anyways, here are a few questions I've come up with: 1) How is stress, especially chronic, able to change the body and behavior? and are these changes permanent? 2)How does gene activation/expression work and how will knowing how to turn on certain genes help us? 3)This isn't really a single question, but I am also wondering how/if what we will be learning about bio can be applied directly to our lives and if increased scientific literacy will change class perceptions about science and its importance.
