Use the drop-down menus to determine which state of matter is described in each statement. The atoms in a are closely packed, but able to slide past each other. The atoms in a spread as far apart as possible. A has a definite shape and volume. The shape of a can change, but the volume is definite.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

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 =
