The distinction between the terms renminbi and yuan is similar to that between sterling and pound, which respectively refer to the British currency and its primary unit. One yuan is subdivided into 10 jiao (Chinese: è§; pinyin: jiÇo), and a jiao in turn is subdivided into 10 fen (Chinese: å; pinyin: fÄn).
Fleas are attracted to the warmth that the bodies of their hosts emit, vibrations and carbon dioxide, and they also like warm and carpeted environments where their hosts rest. These parasites feed on the blood of their hosts and can cause a number of conditions including skin infection and irritation, loss of hair and lethargy in their hosts.
Carbon Dioxide (from your exhaled breath) will attract mosquitoes. Mosquitoes are attracted by areas that are higher in carbon dioxide (living-breathing animals, humans). Body Heat from circulating blood in animals and humans will attract mosquitoes which have sophisticated heat sensors. They follow body heat and exhaled gases and fly to their target.
