Initially 7000 but I thought they'd probably put the answer as a range so I put 6000
<br>ah i put like 40,000....... i followed the line up......<br>For the "why does the fitness instructor think the resting heart rate does not show who is fittest..." what did you guys put?<br>
It never said other factors were controlled so I said maybe they weren't all at rest but that question was be, it could have been to age aswell but I thought the question was more of an idea's about science question. I did a little arrow for the examiner saying the question wad vague because it annoyed Me :P what did you put?
1) continue the line to show number of extinctions
2) bacteria 6 mark question
