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.
Plants that are adapted to long, dry summers and short, rainy winters are called âMediterranean-zoneâ plants. These include plants that are native to California, as well as those that originated in southern Europe, South America, and other âMediterraneanâ climates. These plants donât need much water in the summer and have thrived in water-scarce conditions for thousands of years. The plants listed below are appropriate for Californiaâs climate and use less water than what you may already have in your garden. This list is a good representation of low-water-consuming plants that are easily available. Check with your local nursery for its suggestions about what is best suited to your area.
