when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

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 =

80cm/s.

24cm/s.

53.3cm/s.
