Passage VII
The male-to-female body mass ratio (MFMR) of a species can be calculated as follows:
MFMR = Mm ÷ Fm
In this equation, Mm is the average body mass of adult males and Fm is the average body mass of adult females.
The figure shows the MFMR of some species within 4 primate groups: apes and humans; Old World monkeys; New World monkeys; and prosimians. A species with an MFMR of 1 is monomorphic with respect to body mass. A species with an MFMR different than 1 is dimorphic with respect to body mass. (Note: In the figure, MFMR values are calculated to the nearest tenth.)
40. Which of the following best explains the units of measure that are associated with the MFMR?
Your Answer is
Correct Answer is F
Explanation
According to the formula in the text, it can be seen that the numerator and denominator are both mass, so ratio has no unit
