I know we have to know how to draw/label beta glucose but do we need to know the same for alpha glucose??

Can someone quickly explain immunological evidence involving precipitates?

IMMUNOLOGICAL COMPARISONS

1. Serum albumin extracted from organism A and injected into organism B
2. Organism B makes antibodies specific to the antigens from A
3. These antibodies from B are extracted and mixed with a blood sample from Organism C
4. This should cause an immunological response in the form of a precipitate being formed (Antibodies respond to corresponding antigens from C)
5. The more precipitate there is, the more closely related the organisms are. This is because there are a greater number of similar antigens

Not much at all on Chapter 13 came up last year, so maybe a lot of that?
Also i'm thinking either meiosis or plant adaptations for the 6 marker

Man. I i wish i did WJEC. That's all I can say.

I worked so hard for this paper, thing is GB might be low but that still doesn't take my frustration away from the sort of questions they ask especially towards the end...

How can they test so little of the syllabus? It is amazing. Tissue fluid hasn't come up for about 3/4 years but they it still doesn't come up.

When is the last time anything about plants came up e.g. to do with xylem? They still don't put in this exam?

So you can get an A in this paper knowing about 60% of the entire content? Makes sense.

I'm sure other people disliked it too... it's like such an odd one to ask....

We have to learn so many different processes but nope they just test us on small really weird pure fact recall.

I found that exam absolutely awful! Hardly any content in it!
I really needed a A/B, i got a D last year and don't think I've done any better to be honest. Im so upset
