Ocean currents and global wind patterns, which are caused by convection currents, most strongly affect a region's

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.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
