I hope we can all come to one giant agreement on what the hell 'chemical composition' meant. Like some said, the elements made it hard to talk about the function in its relation, but 'protein' doesn't seem to cut it as a chemical composition.

Oh and for the hormones one I wrote:

produced by endocrine glands
receptor specific
travel in blood
involved in growth etc
protein molecules

But I dont know if thats what it was asking.

lol that hormone question was waaaaay too ambiguous.
I can't even remember what I wrote, I like crapped on explaining everything I knew about hormones rofl. One thing I do remember writing is how nerves can produce neurohormones, meh.

for hormone i think i wrote: a signalling molecule that produces a change in the function of cells. A hormone can either act on the cell its produced by, cells nearby it by diffusing through intercellular fluid or cells in another part of the body by travelling through the bloodstream.

I think i overdid it =S

target tissue, organ, or cell,
