Thanks to TheOptimist for a scan of the MC section:
Ok so here is a scan of it, note that I only took about 3 minutes doing this and my scanner is not the best in the world :)

They weren't that bad, but the question about biscuits and how it modelled natural selection really confused me... Which one was the answer anyway?

Some of the multiple choice questions were confusing. For the biscuit one I put that the various species did not have the same chance for survival. It just seemed to be the best answer at the time.

I think thats wrong, because in real life different species don't have the same chances of survival, so if the biscuits did have the same chance it wouldn't be a very good model. I'm pretty sure the correct answer was the one about how the biscuits couldn't reproduce/pass on traits/genetic information, whatever the wording of it was.

The one about water retention in the blood???

There was an answer about ADH but that was that ADH stopped being released when the question asked about what can cause an increase in water retention :S

Re: General Thoughts: Biology

I agree, there were some questions in the multiple choice that had no clear answer that stood out, but by applying process of elimination they were doable.

I put down the increased length of that tubule that the water moves out of back into the body, cuz if it's longer there more surface area for water to pass through
