Rheumatoid factor (RF) is a blood test that measures the amount of the RF antibody in the blood.
Weight ranges from about 7 to 12 kilograms (15 to 26 lb) in females, and from 9 to 18 kilograms (20 to 40 lb) in males.[4] Where does a serval live? The Serval lives in Africa.
Unlike the Cheetah Acinonyx jubatus, Servals do not use their long legs for speedy chases. Instead, the legs lift them up on miniature stilts. They are used in the long grass or reeds as the Serval moves along in a series of high antelope-like leaps, from one to four metres in length and up to two metres high.
