Can a hypothesis encompass more than 1 point? I have a SAC on movement across membranes [osmosis]; can my hypothesis be broad like: 'Water will diffuse from an area of low conc. to high. conc.' or should I also mention tonicity [hyper,hypo,iso] ?
Also for aim, do we have to talk about the effect of osmosis on X or just investigating osmosis in X ?
And can a potato piece be referred to as a plant cell or should I refer to it as a piece of potato?
That depends entirely on your Prac. Be specific, but not overly specific. Also, don't mention too many points in your aim or hypothesis. I referred to the pieces of potato as potato tuber cells and plant cells at times (depends on the Prac though).
and what it is we have to know on the proteome and proteomics and conjugated proteins??
You need to know their definitions and worldly importance, I guess. The proteome refers to the entire array of proteins expressed by an organism. Proteomics is the study of the proteome and is important for a number of reasons; the mains ones being that proteins are interlinked and don't act in isolation. Proteomics is promising because it can tell us whether or not drugs tested in humans will have the same effect on animals. Conjugated proteins have a non-protein (prosthetic or non-amino) component in them. For example, haemoglobin contains the heme prosthetic group that contains iron. Other well known examples of conjugated proteins are lipoproteins, glycoproteins and phosphoproteins.
