Title: Edexcel Biology New Specification - Predictions for paper
Post by: vanibharutham on January 11, 2010, 03:26:21 pm
Hey,

i was wondering if anyone could help me with the biology experiments. Especially when they say:

"• Identify any potential errors in readings that can be systematic (values differing from the
true value by the same amount) or random (values equally likely to lie above or below
the true value)."

Im guessing the experimental question tomorrow wouldnt be on Vitamin C... but it could come up...

So Daphnia and Enzyme concentration seems quite likely to show up

so any suggestions on the questions and how to increase the reliability etc?

Also seeing that there was a question on prenatal testing last year,

i assume that there might be a question on Gene Therapy...

any ideas other than that?
