Hey there!
El Nino typically involves waters with a warmer than usual surface temperature, a flatter thermocline (cooler water moves to the surface), and weaker trade winds. As for La Nina, think of it as the opposite of El Nino. There will be stronger trade winds, and cooler surface water temperatures.
Hope this helps!
When testing diffusion over a selectively permeable membrane, the proper setup is aimed at putting different concentrations into tubes and the same water volume.
<h3>What is a selectively permeable membrane?</h3>
A selectively permeable membrane is a physical barrier that allows the passage of certain substances but not others.
The cell membrane is a selectively permeable membrane that cells need to interchange nutrients and waste with their environment.
In conclusion, a suitable experiment to show the process of diffusion in a selectively permeable membrane is to put concentrations of the solute into tubes and the same volume of solvent (water).
