What are the advantages of using compact fluorescent light bulbs over standard incandescent bulbs?
The average incandescent light bulb is wasteful; about 90 percent of the electricity it uses is lost as heat and only 10 percent turns into light. New compact fluorescent lamps are much more efficient. One of these 18-watt bulbs produces as much light as the standard 60-watt bulb, and it typically lasts 10 times as long. While you initially pay more for the new bulb, it will save you as much as $50 in electrical bills and incandescent-bulb replacement costs over its lifetime. Perhaps more important, a compact flourescent bulb will generate less pollution from power plants during its lifetime of use than an incandescent bulb; as much as 1,500 pounds less carbon dioxide and 20 pounds less sulfur dioxide will spew into the atmosphere.

In response to signals from the creatures´ hormones and nervous system, pigments in these chromatophores move towards the surface of their skin. This shifting of pig
