<span>The answer is sympatric
speciation. This is differentiated from allopatric speciation that involves the
divergence of a species due to the separation of parts of the population by a
geographical feature (such as a valley of the mountain). In sympatric
speciation, the divergence may be due to behavioral and reproductive isolation
within the population</span>
Explanation:
In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.
