Cells can benefit from diffusion even though it occurs naturally without action from a cell. How can cells benefit from diffusion? Cells increase concentration of needed molecules such as oxygen.

Cells decrease concentration of waste molecules such as carbon dioxide.

Cells achieve balance with their environment to maintain equilibrium.

All of the above are correct.

Plants can have a positive and negative effect on the rate of weathering

Nwhat way does renewable energy differ from nonrenewable energy?

Sandstones that form in aeolian (wind/desert) environments appear very different from other sandstones, such as those formed in a beach/ shoreline environment and in rivers on land. give three identifying properties for each of the three sandstones that would tell a geologist which depositional environment they formed in. consider things such as the relationship between transportation and grain size, shape, roundness, sorting, fossils and composition.
