which type of star would mostly likely turn into a black hole if it pulled in mass from a companion star?

answer:

stellar black holes are therefore most easily found in x-ray binary systems, where gas from a companion star is being pulled into the black hole.

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 =
