"Changing concentrations" refers to the process of altering the amount or proportion of a substance or component present in a system. It indicates the transition from one concentration level to another, either by increasing or decreasing the quantity.
Full definition
What I would like to see posted would be an extension of your maths section to show the methods used to calculate the effect of
changing the concentration of CO2 in a model system.
My interest in carbon dioxide concentration as a variable evolved from the recognition that the
rapidly changing concentration of carbon dioxide in the atmosphere was likely to disrupt the relationships between plant physiological processes and adaptations to the environment that I had been studying.
Of course, many molecules are
expected change their concentration over the critical period, and many of them could be just going along for the ride without playing a role in critical period closure.
Higher carbon dioxide
levels change the concentration of ions (electrically charged atoms and molecules) in the fishes» blood, altering the way that the neuroreceptors work.
That would be fascinating; extremely localised methane detection could indicate that there are pockets of methane production... or perhaps a change in wind
direction changes the concentration of the gas in the air?
Forced changes in irradiance are not only affected
by changing concentrations of constituents or other external sources, but also by changes in water vapor and clouds.
The researchers even found that by
changing the concentration of copper present in the outer beams, they could tune the extent to which these structures shrank.
You should not boil the water more than once, as this can
change the concentration of minerals in the water.
Changing the concentration of the enzyme's substrate molecule in the model produced an outcome that described how ATP synthase interacts with its microenvironment.
Adjusting the amount of ATP dictates how long the drops move for, and
changing the concentration of tubes affects the way the gel churns.
By performing experiments in the precisely controlled environment of the CLOUD chamber, the project's scientists can
change the concentrations of chemicals involved in nucleation and then measure the rate at which new particles are created with extreme precision.
In 1896, the Swedish chemist Svante August Arrhenius proposed that
changing concentrations of CO2 in the atmosphere would lead to more temperature variability in the poles.
Moreover, a cell culture constantly alters its own environment —
changing the concentration of oxygen, carbon dioxide and nutrients significantly over time.
And basically,
changing concentrations of CO2 have done absolutely nothing to hurt the Emperor Penguins.
Seven global vegetation models are used to analyze possible responses to future climate simulated by a range of general circulation models run under all four representative concentration pathway scenarios of
changing concentrations of greenhouse gases.
«The primary quantity directly affected by
the changing concentration of greenhouse gases is temperature.
