Explanation:
diffusion is movement of molecules from a region of higher concentration to a region of lower concentration
2a)molecules will be moving out of the cell
b)molecules will be moving into the cell
3i)molecules will be moving into the cell
ii)molecules will be moving out of the cell
iii)there is no movement since concentration is equal inside and outside the cell

The three-dimensional compositions have more silicon in comparison to those composed of independent tetrahedra.
The silicate minerals refer to the most general of Earth's minerals and involve feldspar, quartz, mica, pyroxene, amphibole, and olivine. On the other hand, the silica tetrahedra composed of oxygen and silicon, produce sheets, chains, and frameworks, and bonds with other cations to produce silicate minerals.
