In an experiment over osmosis, animal egg cells were placed into different solutions. Water was observed moving into and out of the eggs. What caused the water to move?

a
The plasma membrane used energy to move the water to equlibrium
b
The cell used selective permeability to get a drink of water
c
The different solutions created a concentration gradient and water naturally seeks equlibrium
d
The salt or sugar pushed water into the cell

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.
