    It's not cells, the only cell in B1 is the light receptor cells in the eye, it's in nerve and hormones I believe
    hmm possibly, its just annoying how the light receptor bit isnt in the text book and AQA recommend this book so yeh

    I think I also ticked the third one (the one where the middle bar was the largest?)
