I NEED THIS TURNED IN RIGHT NOW I WILL MARK YOU THE BRAINLIEST NO LINKS Draw a force diagram on the object in the image. Identify 4 forces acting on the object, draw an arrow to represent their strength and direction. Label each arrow with the type of force.

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 =

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
