The Zerons have the same photo transduction mechanism as humans but instead of rhodopsin, their active photo pigment is called zirtricon. This pigment gets activated upon receiving a spectrum of wavelengths that does not exist on earth. Considering that the rest of photo transduction pathway is the same as in humans, what device or molecular therapy would you design to allow photo transduction (activation of zitricon or anything else along the pathway of photo transduction) to occur in Zerons' retina to allow a Zerons to see on earth should you invite one to earth? Clarification: Think of the photo transduction pathway and all the steps in it and at what step or steps could you intervene with your scientific genius allow the cascade of events to occur to allow an action potential to be generated in the ganglion cells of Zerons' retina.

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.
