When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.
A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.
The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.
An<u> </u><u>isotonic solution </u><u>does not generate gradients</u>, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.
The goal of mitigation is to avoid significant human interference with the climate system, and “stabilize greenhouse gas levels in a timeframe sufficient to allow ecosystems to adapt naturally to climate change, ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner.
