explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

a 2,000 calorie based diet.

technology is the application of the knowledge gained by science.

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 =
