9 possible outcomes.
1. There are two coins being flipped.

HH (two heads) HT (heads and tails) TT (two tails)
There are three sides to the spinner
Possibilities:
Side 1 Side 2 Side 3
Since there are 3 possibilities for each, multiply them together
So, 3*3 which equals 9 possibilities

2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
To maintain pressure within plant cells and keep structure while growth ensues. Good luck, milady. *Tips his fedora*
