AQA AS Biology

Untitled.jpg

need help with this question ty:h:
As there are 60 minutes in an hour you need to divide each of the numbers that are in the second column (Mass of sucrose hydrolysed by SPS in 1 hour/micrograms) by 60. So your rates from top to bottom in standard form should be:

1.17x10-3
1.50x10-3
1.83x10-3
2.50x10-3
3.33x10-3
4.00x10-3

All my answers are to 2 decimal places because the second column has data to 2 decimal places
Hope this helps :smile:

It would be great if rather than just giving the answers like this you could encourage the OP to find the answer for themselves - after all, they won't have you in the exam to do it for them! Thanks :smile:
