How long do casts of impressions need before they can be analyzed? 5 minutes 1 hour 5 hours 24 hours

Casts of impressions need 24 hours before they can be analyzed.

First thing investigators should do is to secure and preserve the crime scene area in order impressions (footwear, tyre, ..) not to be disturbed or overlooked. Casting is used in muddy conditions to recover larger, three-dimensional impressions such as tire marks or footprints.

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.

the answer is "a.) well–developed vascular system."
