Exocytosis is basically when your vesicles transport materials out of a cell.
Once the neurotransmitters are synthesised and packaged into vesicles, they are transported until the vesicles reach the cell membrane. Then the 2 bilayers rearrange themselves so that the vesicles are able to fuse with the membrane . Once that occurs, the neurotransmitters will spill out whatever it was carrying.
Two examples of exocytosis are
1) your nerve cells releasing transmitters (explained in the description above)
2)your T cells sending vesicles filled with enzymes to viral infected cells
Answer:
Coal is mined in two different ways: from deep underground and in
strip mines. In both cases the land that is mined is leased by the coal companies, while the ownership remains in public hands. Deep mines are reached through a shaft into the ground, through which miners gain access to the coal seam and out of which comes the coal. Strip mines are used when the coal seam is near the surface. The topsoil and other overburden materials are removed by giant power shovels and piled out of the way. The shovels then dig out the coal. After the coal has been mined, there may be environmental reclamation to return the land to its original state, thus allowing others continued use of it for their own purposes. This involves refilling the hole, spreading topsoil, and then planting new vegetation on it.

It arranges as 2 layers of phospholipids where the hydrophilic(water-loving) heads face toward the outside and the hydrophobic(water-hating) tails are on the inside. They arrange like this to allow for selective permeability which is why this is what a cell's plasma membrane is made up of.
