Urgent ocr question

Hi guys,

I am in need of help with the following questions TO DO WITH CELL MEMBRANES:

Using the freeze fracture electronmicrograph evidence and 'NMR and X Ray diffraction evidence',

How is each of the models the cell membrane, including Singer and Nicholson's, and the Plasticine model, supported or undermined by all the evidence now available?

Which do you think that is the most useful model? Justify your answer.

Thank you!
