1.) Cellular Transport a.Osmosis Osmosis is the diffusion of water molecules across a differentially permeable membrane from a region where water molecules are more concentrated to one where they are less concentrated. The transport of water is simple the cell being selectively permeable will allow water through it until an equilibrium is reached and at that time water will flow both in and out of the cell maintaining the equilibrium. For example a red blood …

…is an overpopulation somewhere it is quickly taken care of and the balance is restored. c.Surprisingly the effects would not be that great because the snails that feed off of the toxic material would die off or adapt to it until it stopped, the lake trout would of course just find another food source until the balance was restored. Even if the effects of the toxin were great eventually a balance would be restored.
