Hormones are the intercellular signal discharged into the blood by specific cells, they travel some distance in order to reach their target tissues and to perform other specific activities. Autocrine refers to the intercellular signals, which are discharged by the cells in a local area and affects the activity of the similar type of cell from which it was discharged.
Paracrine refers to the intercellular signals, which are discharged by the cells and influences other kinds of cells locally without being transported into the blood. Pheromones refer to the intercellular signals secreted into the surrounding and change the behavior and physiology of other individuals.
Neurohormones or neurotransmitters are the intercellular signals produced by the neurons. Of the mentioned intercellular signals, the "e" signifies neurotransmitter.

Answer:
When Kelly drew the diagram, the area marked Y -which includes cast and print- involves mold filling minerals and sediment (option D).
Explanation:
A fossil is the evidence found of an organism that lived many years ago, and consists of organic remains - such as bones - or impressions that remained in the soil.
The fossil record of a living being occurs when it dies and its remains, which are buried, when decomposing leave an impression. This impression - as a mold - is subsequently occupied by minerals and sediment that describe the approximate form of the organism.
In the Kelly diagram, the <u>area labeled Y shows not only the impression of the organism that was found, but also the minerals and sediments that were responsible for filling said mold</u>.
