The diagram below shows the layers of a rock having a trilobite:                               image 1which statement about the rock fossils is true? fossil b is older than fossil a. fossil a is younger than fossil c. fossil c belongs to the same period as the trilobite.                                                    fossil b belongs to the same period as the trilobite.

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.
