Which statement is true about a body moving at a constant speed in a circle? A. It has no acceleration. B. It has an acceleration directed radially and outward. C. It has an acceleration directed radially and inward. D. It has an acceleration directed tangentially.

the results is a decrease in air temperature with an increase of altitude.

explanation:

temp rises, and expansion

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 =
