The first line was interphase not replication.

I wrote dna replication in interphase so should be alright?

Thought I was doing a paper which had more f211 f212 f214 combined than f215, quite heavily synoptic I thought

Posted from TSR Mobile

Exactly what I thought during the fkin thing!
Whats the f point calling it f215, when it has hardly any of It in it, they say they are changing exams to all units all in one... Looks like its already like that now!

Suggest suggest suggest... and stuff that is in AS specification like asthma, that exam was horrible!

Ikr. What's the point of revising the unit 5 content if half of the things don't come up -.-

ThatWasHard!

I reckon the grade boundaries will stay the same or go down. The odd TSR troll will come up with some bs about it being 70 or something, but I reckon it was a challenging paper with many suggest questions and AS specification questions. I wouldn't say it was theoretically tough, but it was challenging.

escpae reflex
habituation
taxis
insight learning
imprinting

Instead of habitaution I put classical condition he compares the CD and his home as a neutral stimulus eh :s-smilie:

And for the insight learning i put operant due to him getting the food through reward if he does it correctly

Why did you do that?

The formula was given on the previous page. You just had to add the totals on the last column of the table
