1. the diagram compares diffusion of sugar
molecules and osmosis. explain the difference
between osmosis and diffusion in cells.

In biology, this is a difference between the two processes. One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

b. climate change will cause an increase in biodiversity of all ecosystems.

hope this
