Answer:
chemical reactions change reactant and produce new substance called products.
Explanation:
chemical reaction is a change which will produce a new substance. ( while physical reaction does not produce a new substance.
You didn't give any statements but, temperature is the measure of the amount of heat in a substance or object. Heat is <span>a form of energy associated with the movement of atoms and molecules in an object. </span>

What percentage of the CO2 in the atmosphere has been produced by human beings through the burning of fossil fuels?
The correct order is:
- Action potential arrives at the axon terminal.
- Calcium ions enter the axon terminal.
- Synaptic vesicles fuse to membrane of axon terminal.
- Acetylcholine is released into the synaptic cleft.
- Acetylcholine binds to its receptors on the junctional folds.
- Junctional folds become depolarized.
- Action potential is initiated on the sarcolemma.
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. Neurotransmitter binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell).
