How does the sun provide energy to drive the earth's weather phenomena? a) temperate conduction from the sun drives the weather. b) the sun's uv radiation warms the air, land, and water. c) emissions from the sun define the earth's energy core. d) gamma dispersion cools the atmosphere, land, and water.

B

Explanation:

The sun's UV radiation warms the air, land, and water.

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 =
