Answer:
Ethyne is useful for artificial ripening and preservation of fruits. It is useful in acetylene lamps to generate light. Ethyne is used to prepare various organic compounds. It is also useful to manufacture important organic compounds like acetic acid, acetaldehyde, ethyl alcohol and polymers like PVC, etc.
Explanation:
Since ethyne burns with a very hot flame, one of its most notable applications is in oxyacetylene gas welding and oxyacetylene gas cutting. When ethyne is subjected to combustion with oxygen, the flame created is known to have a temperature of roughly 3600 Kelvin.
Smooth muscle cells are contractile and will contract from many different agents such as hormones travelling in the blood and neurotransmitters from the autonomic nervous system. The smooth muscle cells are coupled together so that when one cell contracts, the contraction is relayed to the next. This contractile ability is important in the vascular system as it helps regulate blood pressure by changing the size of the lumen of the vessel.
