Explanation:
The stratum corneum, which is the outermost epidermal layer, consists of dead cells
Answer: Erosion and deposition
Explanation: As the water ran through and against the river banks and land, it slowly begins to erode. Also, as deposition occurs (Deposition-When a river deposits the silt and other things in it out into the ocean or where ever it empties.) it creates a delta.
The answer is two molecules each will have one original strand and one new stand.
The correct answer is: Release of neurotrasmitters from the synaptic vesicles
Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine), Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells.
