comparison to the paracrine system? (there may be more than one answer) Hormones are less stable than paracrine signals Hormones have a lower affinity for their receptors than paracrine signals Hormones are produced in a greater quantity than are paracrine signals Hormones are produced by most cell types; paracrine signals are only produced as a response to an insult (wound or infection). O Hormones are produced from cells at a greater distance to their response elements than paracrine signaling.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
