  1. AQA June 2013 Biology B3 Q6b Suggest an explanation for an athlete overheating in humid conditions.

  2. AQA June 2013 Biology B3 Q6b – Mark scheme

  3. AQA June 2013 Biology B3 – Examiner’s report “Q6bMany students failed to gain the second mark point because they didn’t expand on the idea of poor evaporation being due to high humidity – simply saying evaporation is less in humid conditions was not sufficient to gain the second mark point. There were a number of incorrect responses that suggested there is less oxygen in humid air because of the water content which decreases respiration rates. There were also suggestions that the water particles in the atmosphere were warm and that they are absorbed by the skin, heating the athlete up.”
