Answer:
Speed
Explanation:
Aliyah must have been trying to find her speed.
The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,
speed = 
with a unit of m/s.
<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>

anyways: Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
The answer is c hope this helped
The organism could adapt over time and find another way to satisfy this need, it could move to a new location, or the organism could eventually die off.
Answer:
0.216
Explanation:
The mole fraction of HCl is the number of moles of HCl (0.99) divided by the total number of moles in the solution.
mole fraction = (0.99)/(0.99 +3.6) = 0.2157
The mole fraction of HCl is about 0.216.
