SOAL TOEFL(READING 10)

                  Bloodhounds are biologically adapted to trailing their 
             The process by which the nose recognizes an odor is not 
             fully understood,but there are apparently specific receptor
             sites for specific odors.In one explanation,recognition 
 line      occurs when a scent molecule fits into its corresponding 
             receptor site,like a key into a lock,causing a mechanical or
(5)        chemical change in the cell.Bloodhounds apparently have 
             denser concentrations of receptor sites tuned to human 
             scents.
                    When a bloodhound trails a human being,what does it 
             actually smell?The human body,which consists of about 60 
             trillion living cells,sheds exposed skin at a rate of 50 
             million cells a day.So even a trail that has been dispersed 
(10)      by breezes may still seem rich to a bloodhound.The body 
             also produces about 31 to 50 ounce of sweat a day.Neither 
             this fluid nor the shed skin cells have much odor by 
             themselves,but the bacteria working on both substances is
             another matter.One microbiologist estimates the resident 
             bacteria population of a clean square centimeter of skin
             on the human shoulder at”multiples of a million.”As they 
             go about their daily business breaking down lipids,or fatty
(15)      substances,on the skin,these bacteria release volantile 
             substances that usually strike the bloodhound’s nose as an 
             entire constellation of distinctive scents.
