I'm pretty sure that the 6 marker explicitly emphasised a "rapid response" which is characteristic for reflex responses, so you talk about the reflex arc.
Btw, am I the actually the only one who doesn't loathe P5
So I was correct to link the sensory neurone to the CNS (brain) and then the relay to spinal cord and then motor to effector? YES!

What are you, satan?
Lol then again I do gcse electronics, so it should be my strong point(I hope )

Reflexes don't go through the CNS I don't think? I think you will have got 4 or 5 marks but I think it as:

stimuli-----------Receptor----Sensory neurone-----relay neuron----------motor neurone---------effector-----------response

It's hard for me to comprehend why anyone would willingly do GCSE electronics xD

The question was:

"Animals respond to changes in their environment. A predator appears and causes a rapid response in a squirrel. Suggest what this response might be. Describe the processes that occur in the squirrel to cause this rapid response."

Aha electricity and circuits isn't that bad! You actually get used to all the terminology and how they work e.g current, resistance, p.d, resistors, motors etc. Or maybe it's just me?

Relay neuron is within the cns, so they technically do, I made the mistake of differentiating the 2 in the exam :rolleyes:

I'M STILL ON P5 hahaha
Hah, at least you'll know it well it really is badly explained to be honestbecause the science is trickier :/ I'm just gonna have to do loads of practice with it :/

Has anyone done the January 2013 physics paper? It's so ****ing stupid the questions make no ****ing sense whatsoever! Every physics exam tries to **** you over one way or another

I'm feeling a little more confident with this exam, surprisingly! A day before the exam and I'm finally comfortable with the topics....oookay then, logic..

And so is the way of physics :rolleyes: I'm guessing you're buzzing for the exam tomorrow

I don't understand it despite studying it for ages!

Yeah, I'll do what you're doing too :confused:

It was heaven compared to June 13! 6 markers are fairly nice..the P5 one is fairly dodgy but all we really need to know is that stationary ions in the wire collide with charges which creates kinetic energy and thus heating. And add some data in!

The question was:

"Animals respond to changes in their environment. A predator appears and causes a rapid response in a squirrel. Suggest what this response might be. Describe the processes that occur in the squirrel to cause this rapid response."
The rapid response bit implies it was a reflex, where the information isn't processed. So I don't think you talk about the CNS as the brain doesn't decide what to do, as it is involuntary. IDEK, you have an impressive memory to recall that question!

I just had a look at the spec and you are correct that relay neurons are in the CNS, so it isn't wrong but I don't think you talk about it co-coordinating a response or anything as
understand that this arrangement of neurons into a fixed pathway allows reflex responses to be automatic and so very rapid, since no processing of information is
required

I've looked at it and I just think... what the hell. The questions seem to want answers that you'd never think of and the marks awarded for some points is ridiculous.
