Answer:
Combustion of a substance
Explanation:
Johann Becher in 1669 proposed that all the material are composed of the rocks, water and the oils present in the Earth.
When the material is burned, the oil present in the material which is responsible for the combustion. The oil is escaped into the atmosphere which is released through fire and flames are the signs that it is releasing.
In 1703, George Sthal renamed this combustible component called the "Phlogiston" which is taken from the Greek language to refer in flame.
Therefore, phlogiston is responsible for the combustion of a substance.
1) An action potential is propagated down the lower motor neuron
2) Calcium levels increase in the cytoplasm of the muscle cell
3) Acetylcholine binds its receptor and causes depolarization
4) Vesicles containing glutamate fuse with the nerve terminal
5) Contraction.
Answer:
4,1,3,2,5
Explanation: Glutamate is the neurotransmitter that excites the motor neurons and produces action potential in motor neurons. Then this action potential travels down towards the axonic terminal where it would cause release of acetylcholine. ACh then binds to postsynaptic membrane causing depolarization of sarcolemma. Calcium ions are released into the sarcoplasm resulting in muscle contraction.
