Thermoplastic is known to be a plastic material with a polymer that can be molded above a specific temperature and solidifies upon cooling. Thermoplastics can be remelted or reshaped by heating and they have low melting points. Furthermore, they usually have high concentration of polymers with amorphous structures, the material will have a poor resistance to loads but it will have an excellent elasticity.
Answer:
C. Synthesis of organic molecules
Explanation:
According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
The neurons conduct impulses over relatively long distance in the body. This is facilitated by their long cytoplasmic extensions
