ASAP!!! 40 pts!!!!!! for original answer!!!!!!!

1 ) Explain how the surface area and volume of cells affect the rate of exchange of materials in and out of cells in multi cellular organisms.


2) Ribosomes → rough endoplasmic reticulum → vesicle → Golgi apparatus → vesicle → within the cell or outside the cell.

Explain where in this pathway the process of exocytosis plays a role.


3)The important factor in osmosis is not the number of molecules. Instead, it is the number of particles in a given volume of solution. For example, one glucose molecule dissolved in water yields one particle, but one NaCl molecule can yield two ions: Na+ and Cl-. Water moves osmotically in response to the total concentration of particles in the solution.

If there is a 10% glucose solution on one side of a semipermeable membrane and 5% salt solution on the other side, what will most likely happen to the flow of water?
