Answer:
When light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule
Astronomers have seen stars forming within a nebular cloud. As the nebular cloud condenses and its own gravitational attraction collapses it, heat and energy build up creating a planet.
The answer is B, osmosis is the movement of water. Diffusion is the movement to chemicals and molecules.
Both osmosis and diffusion are movement of molecules from a region of higher concentration of the substance moving to lower concentration down the concentration gradient. However, osmosis is only for the movement of water molecules, while diffusion is for any type of substances including liquid or gas. So we can also say osmosis is a type of diffusion actually.
And also, both of these movement of molecules does not require extra energy, they all happen due to natural tendency.
