Answer: Osmosis
Explanation: Osmosis is a process in which water move from an area of low solute concentration to an area of high solute concentration through a selectively permeable membrane. For osmosis to occur, it must be through a selectively permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
<span> It is erosion by wind of loose material from flat areas of
dry, uncemented sediments such as those occurring in deserts, dry lake
beds, floodplains, and glacial outwash plains.
So the answer would be A

The answer is the Phloem. Food=Phloem
Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
