A simple solution is basically two substances that are evenly mixed together, but the mixture is homogeneous. Meaning, you can no longer tell the two substances apart once they are mixed in solution.
This is because the solute dissolves in the solution.
A solute is the substance to be dissolved (sugar).
The solvent is the one doing the dissolving (water).
As a rule of thumb, there is usually more solvent than solute.The amount of solute that can be dissolved by the solvent is defined as solubility.
Answer:
c. a proton gradient set up across the thylakoid membrane
Explanation:
During the photosynthesis (this also occurs in cellular respiration in mitochondria), hydrogen ions (H+) move across the thylakoid membrane down their electrochemical gradient (from the area of their higher concentration to the area with hydrogen ions lower concentration). An ion gradient can be used for the production of ATP.
