Answer to Question #267265 in Cell Biology for isa

Question

hile proper filtration technique showed the location of the dye, it did not explain the process by which the dye moved to that location. Provide evidence that the dye moved to that location by active transport and not by simple diffusion.  

Answer 1

Active transport has movement of ions in a gradient of lower to higher concentration using energy . Since the color change i.e since the color of solvent turns out tonbe orange yellow/ pink red and from lower to higher pH it is clear that this is active transport.
