I believe it is called Human Sexual Response cycle.
Vitamin-like is the answer.
<span>Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to "move" in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white, pink, or red. Pink flowers may be the average phenotype, but if we start to remove red flowers from the population, the "mean" phenotype will be shifted toward white flowers.
In disruptive selection, the average phenotype is selected against. This produces a "two-humped" bell-type curve, and the greater distribution is split between the two phenotype extremes. If we have the same type of incomplete dominance as mentioned in the previous paragraph, assume that the pink flowers are selected against. This means that the two "humps" shown in the distribution will be centered around the red and white phenotypes.</span>
Littoral cells are the areas of the coastline where sediment is constantly being moved in and out. This is usually done by waves and currents. The main reason for this is to keep the coastline from eroding away.
The movement of sediment along the coast is primarily controlled by the processes of erosion and deposition. Erosion is the process by which wave action and other agents break down and wear away rocks and other materials. This process typically occurs along the shoreline, where waves crash against the land.
Deposition is the process by which eroded materials are transported and deposited elsewhere. This can occur either offshore, where materials are carried by currents and then deposited on the seafloor, or onshore, where materials are transported by currents and then deposited along the shoreline.
The movement of sediment in and out of littoral cells is an important part of the sediment budget. The sediment budget is the balance between the amount of sediment that is being eroded and the amount that is being deposited. Littoral cells are areas of the coast where sediment is constantly being moved in and out. These areas are usually located near river mouths or along the shoreline.
