If you go to a biology lab and put some living cells in a flask and you return after some days, how can you distinguish which cells are alive and which are dead? The answer is that living cells attach strongly to the flask wallls, while dead cells are floating in the fluid.
That would depend on the organism... many of them would just be suspended within the fluid.
This is done by reactions that promote the function of adhesive molecules.
I doubt it. Evidence?
Cell-cell adherence is one of the basic properties of living cells.
Um, most life is single-celled. So no, that would not be a basic property.
This is the reason why our body is held together and not spontaneously decomposed
There's a lot more to it than that. Your skin is held together by connective
tissue, which is held together by fibroblast cells. They have fibers that connect to a gel-like substance between them, so its not cell-to-cell adhesion.
