I never talked about ADH, just TSH and the Growth Hormone (is somatrophin the same?) but hopefully I got 4 marks for that. I wrote less for the second part but I was quite specific about effects on root, shoot, lateral buds, leaf fall, fruits and stuff.
Hippo, are you talking about the one where it said why the lymphocyte would reject or the last bit about overcoming rejection?
I said that Lymphocytes recognised the tissue as being foreign due to the unfamiliar antigens of the tissue and the fact that the lymphocyte would make antibodies to destroy the tissue.
I said immunosuppressor drugs for the second bit, but it required some thought

I don't think I put stay the same for any of those.
Incidentally someone's phone went off today in the exam and the invigilator was like "who was that, own up now, your exam is going to be cancelled." He seemed very surprised that no one admitted to it!

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!

Was that the question about differentiation in xylem?

we did learn that. differentiating the cells didnn't we??
I didn't cover how xylem was differentiated in class.
