If you already knew that the infectious agent was either bacterial or viral, which treatment would allow you to distinguish between these two possibilities?
a) i
b) ii
c) iii
d) iv
e) either ii or iv

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.

i am going to guess that it is co2.

the answer would be knowledge about cars!

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
