Which of the following is the law of moment in balanced condition? a. ExLd=LxEd b. ExEd=LxLd c. E/Ed=L/Ld d. E/Ld=Ed/L

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
