The graph is the path beth took on a walk.

a graph with horizontal axis time (seconds) and vertical axis position in (meters). the line runs in 2 straight segments from 0 seconds 2 meters to 6 seconds 8 meters to 10 seconds 0 meters.
what does the line from time 6 to 10 indicate?

beth slowed down considerably.
beth went back toward her origin.
beth sped up considerably.
beth went farther away from origin. h expression is equivalent to

Beth went back toward her origin

Explanation:

Please, see the attached image that represent's Beth's path.

She started her walk 2 meters from the origin (0) and after 6 seconds she headed back to position zero (0) the origin. Notice the second half of the graph as a segment going down, thus reducing her distance from the origin, and getting closer to it.

Beth went back toward her origin.

Beth speed up considerably.

Explanation:

speed of the object is defined as the slope of the position time graph

here we know that

initially it moves from t = 0 to t = 6 from x = 2 to x = 8

so the slope is given as

similarly for next we have

again it comes to x = 0 after t = 10 s

so the speed is

so here the velocity is negative which shows that it will move in reverse direction also its velocity is also increase

so correct answers are

Beth went back toward her origin.

Beth speed up considerably.

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 =
