knocking out as in PRDM16 one ?
it means TURNING OFF the gene.
it says that if we turn off this particular gene in BAT the heat producing ability and capacity is lost owing to the abnormal growth of BAT, this shows that PRDM16 is important in development of normal BAT.

How is that wrong? :s


If neurotransmitter substance is released into the synapse with the bipolar neurone, no action potential can be fired in the bipolar cell to the optic nerve but the SNAB book says action potential IS SET UP in the bipolar neurone. This is wrong. Look in the SNAB revision guide it contradicts this by saying if neurotransmitter is released no action potential can be triggered in the bipolar cell, the cgp book contradicts this as well as sir valentine dude. So 3 against 1 lol, its obvious the snab book made a mistake there
Anyone have the grade boundaries for the Summer 07 and 08 exams?
They're not on the Edexcel website as they're old spec. :frown:

Quick question:

in fMRI scan if the there is greater activity then, there is more oxyhaemoglobin which does not absorb radio waves, so will you see the area light up or not?
So everyone has standford article questions
Here are some other me and my friends purchased online

yeh because more radio waves are not absorbed and the detectors can pick this up making the area light up on the screen on a comp
