To find the difference between the high end and low end of the range, we need to know the range itself. Unfortunately, the given information only provides the growth rate of human hair (6.849x10^-4 cm per hour), but it does not specify the range.
Without the range, we cannot calculate the difference between the high end and low end.
Please provide the range data, and we will be able to continue with the calculation.
Human hair grows at a rate of about 6.849x10^-4 cm per hour. The rate depends on gender, genetics, age, and health. Find the difference between the high end and the low end of the range. Express your answer in scientific notation. Do not round your answer.
