Explain how changes in the angle of the sun in the sky during the year affect the temperature on Earth use your own words please

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

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%

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 =
