Which of the following is NOT true about main sequence stars? Group of answer choices

A.) The forces of gravity and nuclear fusion balance so the star does not collapse or explode.

B.) Temperature is directly related to brightness.

C.) The forces of gravity and nuclear fusion are not in balance so the star's core collapses while the outer layers expand.

D.) Temperature is related to size.

their crystal patterns have been disrupted by stress

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 =

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
