Although the model is structural and makes reference to an apparatus, the id, ego and super-ego are purely psychological concepts and do not correspond to (somatic) structures of the brain such as the kind dealt with by neuroscience.
it takes a thousand million to make a billion, so 1,000,000 = 1 million 1,000,000,000 = 1 billion divide 142.98 by 1000= .14298 usually only convert if you have a thousand or â¦more millions. for instance, the US population is 300 million, or .3 billion. but nobody says that.
    1000 thousands = 1 million   1000 million = 1 billion   1000 billion = 1 trillion     This is what I assume to be correct. But then again does it real â¦ ly matter how many billion are there in a trillion.
