QuestionIn 2004, it was reported that "the relationship between body mass, $M$, and standard metabolic rate, $B$, among living organisms remains controversial. However, in many cases $B$ is approximately proportional to the three-quarters power of $M$." (a) Write a function that represents this relationship. If you must introduce a new variable, use $k$. $$B=$$ $\square$ K(M3(4)) (b) The average mass of an African forest elephant is 4.9 metric tons, and that of a typical mouse is 25 grams. Use part (a) to determine how many times greater the metabolic rate of an elephant is than that of a mouse. Recall that 1 metric ton = 1,000,000 grams. $\square$ times greater
