I've created videos for the entire IB Biology SL and HL syllabus that I teach including Options A, D, and E. I have used the powerpoints, notebooks, and other visuals that I normally use in my class and I hope they help in your understanding of the topics. Focus on the BIG PICTURE of biology and you will see how a few major themes run through this amazing field of science. Good luck with your studies and let me know if there is anything that I can do to help you along.
you explain it really good and i appreciate this. it truly made my concept clear but just a tiny little correction, the distance they calcualted was 0.34 nm or 3.4 angstrom, not 3.4 nm thank you for your work thoo
