All you need to do is list 1 organism that uses diffusion and show appropriate diagrams. Write 100 words about the organism but it must include 1 diagram. This would be best for people that know basic biology. PM me if you can do this and tell me your price.
Well .. I know biology and with writing I have no problems yet .. but .. What you mean - "diagrams" ! About what ? What stats you want to see there ?
Just finished my Intermediates last month, so this will be a sap! PM me for confirmation please. Rate is: 0.75 $ per 100 words. By the way: do diagrams have to be hand-drawn or copied from an internet source. Do you want the diagram of the organism - or that of an organism showing the process of diffusion taking place?
