The reaction of a particular endothermic reaction whether in a negative or positive entropy change is always spontaneous. Temperature differences will be spontaneous throughout the reaction but one thing is constant, heat will always be produced within the said reaction.
Hey there,
It is the Turbine and also the generator that converts the movement of water.
Hope this helps

If we had the same climate every minute of every hour tons of carbon would circulate the earth and climate change would make the polar ice caps melt from all the carbon around
The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
Action potential travels through the membrane of the presynaptic cell causing the voltage-gated 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. Neurotransmitter ACh binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
True, the plasma membrane is selectively permeable and controls the various substances that are allowed into the cell and that are allowed to leave the cell.
