Who What When Where Why...and sometimes How???

To be honest I took Bio 12 because I needed an academic...whoops. But Bio is probably the most interesting science (and the one that makes the most sense to me) so yay! And Mrs. Phillips rocks so who wouldn't want to take Bio 12 with her? Double yay! I'm probably the most excited to learn about our SYSTEMS! (nervous systems, reproductive systems...all that good stuff) Because they seem interesting...and i've been using them for 17 years and barely have a clue how they work...seriously though. My #1 question for this year: Where did people get that idea that hearts were shaped like that???
