Answer:
Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.
Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.
Answer:

Answer:
Natural selection
Explanation:
Natural selection favors the individuals carrying the adaptive variations and allows them to reproduce more as their beneficial variations impart them the survival advantage. These individuals with beneficial adaptive traits reproduce more and produce a large number of progeny, all carrying the useful adaptive features of the parents.
Hence, natural selection favors individuals with beneficial variations. The differential rate of reproduction of the favored individuals allows inheritance of favored variations to the future generations.
