The separation of cells and cellular components is accomplished with a centrifuge . A sample of cells is first blended to mechanically break some of the cells releasing their contents to form a cell homogenate The remaining whole cells and cell componerlts are separated based on their sedimentation rate by centrifuging the sample at increasingly high speed . The centrifuge spins at up to several thousand rotations per minute ( rpm ) forcing material to accumulate as a pellet at the bottom of the tube . The liquid portion is removed and centrifuged again to yield four ( 4 ) pellets containing the cells or cell components listed in the diagram

How do water’s relative densities as a solid and a liquid differ from that of most other substances? water’s solid and liquid forms have different densities, while most other substances have solid and liquid forms with similar densities. water’s solid and liquid forms have similar densities, while most other substances have solid and liquid forms with different densities. water’s liquid form is less dense than its solid form, while the opposite is true of most other substances. water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.
