    Hi all, wondering if anyone could help with the questions from the screenshot, they are from page 128 of the Edexcel GCSE(9-1) Biology ActiveBook and I'm having some trouble, any help would be greatly appreciated.

    Questions are on the right, the scenario on the left.

    Thanks again,
    Matty
