Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature of 18.0 ∘ C ∘C at one end and 116 ∘ C ∘C at the other end. Both rods have a circular cross section with a diameter of 5.00 cm

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  

therefore, 100 trillion micro-organisms would weigh:

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 =

where is the

i think the answer is bone
