the cell theory states that all living things including animals, as well as plants, are made of cells.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

a- all cells come from pre-existing cells
