Genetic equilibrium is a theoretical state. It never happens in nature because it goes against evolution.
Here are the five conditions that cause genetic equilibrium to occur:
- No selection
- No mutation
- No migration
- Large population
- Random mating
The answer would be mouth and stomach
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.
