Heard of your page from a friend studying AP Bio. You are making me want to actively study! I really hope I can get a 5! With your help I’m sure I’m a penguin and I’m dressed for success! If I come across any question I can’t do I’ll ask you (if that’s fine)

I remember one practice question I did brought up osmolarity and osmolality. What is the difference between the two? Also thanks for all of the videos and resources you provide!

the only difference between simple diffusion and facilitated diffusion is that facilitated has channel proteins? Also do you need to know how to do the free water potential equations
