(a) Size, density

(b) Sedimentation rate, sizes and density

(c) Size, structure

(d) Mass, size

The question was posed to me in exam.

This intriguing question comes from Centrifugal Seperators topic in section Building Blocks of Dairy Processing of Dairy Engineering

Answer 1

Right answer is (b) Sedimentation rate, sizes and density

Best explanation: Differential centrifugation is a process which is used to separate certain organelles from whole cells for further analysis of specific parts of cells. Differential centrifugation is a process based on the differences in the sedimentation rate of biological particles of different sizes and density.
