B

Explanation:

Unsaturated fatty acids have double bonds. Fatty acids that contain only single covalent bonds between the carbon atoms are called saturated.

there are no details given

explanation:

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.
