The<u> ion concentration</u> in water molecules controls the amount of water in a compartment
The concentration of ions in a body of water determines the rate of diffusion and osmosis that occurs in a body of water contained within a body compartment. which has a direct impact on the amount of water that is held in any water body compartment.
Hence we can conclude that the ion concentration in water molecules controls the amount of water in a compartment.

<u>Question</u>:
Which activity produces the smallest amount of greenhouse gases?
a. driving a car
b. riding a bicycle
c. cooking with gas
d. operating a generator
<u>Answer</u>:
Riding a bicycle produces the smallest amount of greenhouse gases
<u>Explanation</u>:
Cars and other heavy vehicles account for approximately 1/5th of the United States emissions, producing carbon dioxide and other greenhouse gases such as methane and nitrous oxide. Cooking gas too produces a lot of carbon dioxide. Natural gas too basically consists methane in an odourless form and therefore when released produces greenhouse effects and in turn causes detrimental effects on the environment.
The generators that are used both at low scale and also in high level industries is known to produce toxic levels of carbon monoxide and methane. Compared to all these, a bicycle which produces greenhouse gases during its production does not release as much greenhouse gases and the rest.
