The curve that most closely describes the mean tempretire of the fluid as a function of position  along the tube.

Explanation:

Hello. Your question is presenting very confusing words, however, through the context of the question as a whole, it is possible to see that you are saying that the water that enters a circular tube has a lower temperature than the temperature presented by the surface of the tube . In this case, if you are going to present a graph about this, it is important that this graph presents a curve that shows the relationship between the average water temperature as a function of the position of the water along the tube. This graph will be similar to the graph shown in the attached figure below.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).
