They all breathe oxygen
Their body is full of water
Hope this helped :D
That its not in the cell or that its just there or that you can't find it anywhere else but in the body outside the cell....
Answer:
the answer is the 1st one
Explanation:
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).
