Advanced Higher Biology - Pre-Exam Thread

Hi - No one has made one up for advanced yet - so I thought I would?

What do you feel is going to come up?

Also wondering if someone could help me out with this Question from 2004 paper.

It is Question 1diii) in data analysis Question. Asks about how data from the two treatment groups is random. The answer is that in both groups, pre-treatment responses to isoprenaline procedure are about zero/the same/only differ slightly.

How does that work?

Thanks for solutions- think i've done alright except for q8.....thanks rabbit- you 2. I'm worried about essays too but there was a bitch of a DNA one last year so at least that won't come up....best case scenario- essay on nitrogen cycle/succession (which i used to hate)/ something like grazing + parasitism etc.

Yeah, basically as I said in my sleep deprived state last night you have to look at the pretreatment lines, they are virtually the same meaning the subjects must be similar so have been picked randomly rather than so one group will appear to respond better than the other (because it started with a bigger voltage pre-treatment)

So glad they have changed the format so you only get one 15 mark essay q - hated doing 2004, I got 7/15, 15/15 and 4/15 in the 3 essay sections when i did for the first time!

exam is over i found it really easy actually.. how did everyone else do??

There is a post exam discussion thread if you haven't found it, I would post a link but I'm on my ipod
