figureThe plastic behaviour of polymers is also influenced by their morphology, or arrangement of molecules on a large scale. Stated simply, polymer morphologies are either amorphous or crystalline. Amorphous molecules are arranged randomly and are intertwined, whereas crystalline molecules are arranged closely and in a discernible order.
The bristlecone pine is an amazing plant of the alpine biome. It lives in scattered, arid mountain regions of six western states of America ranging from Colorado to California. Many are found in the Ancient Bristlecone Pine Forest in the White Mountains of California.
The state of California (where Wayne's Word is based) includes about 5,000 native and naturalized species, and 41 percent of these species belong to the following six plant families: sunflower family (Asteraceae), grass family (Poaceae), legume family (Fabaceae), snapdragon family (Scrophulariaceae), mustard family (Brassicaceae), and sedge family (Cyperaceae).
