    What did people put the coronary artery question?? I elaborated on the heart not being able to pump blood so tiredness, breathing difficulties etc.

    Also, for pentadactyl limb, it was two marks.. So was saying it was a 'limb with 5 digits', correct?

    Yeah I put increased blood pressure due to decreased lumen size and that leads to CHD and risk of strokes but there will be less oxygen delivery during exercise so that means fatigue and resorting to anaerobic respiration sooner.

    For the pentadactyl limb I also put that but mentioned that it provides evidence for evolution and that we all share a common ancestor.
