Why do areas near the equator have warm climates? Question 4 options:

There is less land near the equator

It snows in areas away from the equator

The equator is closer to the sun than the poles

The equator gets the most sun year round

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

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 =
