Answer:
protons its the flow of electricity but does not controll it
Answer:
The ability to bring water into the gills when the mouth is closed would benefit a bottom dwelling shark or ray, because it would allow them to be more discreet when in the process of catching prey and they would be able to stop swimming. Most sharks have to continuously swim or else they would sink, while being able to bring water into the gills when the mouth is closed would highly benefit them and allow them to stop swimming for a moment.
Explanation:
I am not 100% sure this is the correct answer, but I am currently doing a lab on this, so I am using the knowledge I previously had and online resources. I am pretty confident though.
Note that Facilitated diffusion , Active transport and Osmosis are three different ways of transporting substances across the cell surface membrane.
Facilitated diffusion is the movement of a substance from high to low concentration , similar to simple diffusion , but due to the complexity of the cell surface membrane , polar molecules and ions cannot just pass like that , so they pass through specific carrier and channel proteins in the cell surface membrane and so we call it facilitated diffusion.
For Active transport , it's the movement from low to high concentraion using energy from ATP
For Osmosis , it's totally different . You only name osmosis when its all about water . Its the net movement of water from high water potential to low water potential through partially permeable membrane .
If you're doing AS , you'll be familiar with Endosmosis and Exosmosis.
