Answer:
1) The particle will sink to the bottom of the centrifuge tube.
Explanation:
If the density of the medium in centrifugation is the same as the density of the particle, the particle will remain suspended in the medium.
Centrifugation is a process that separates particles or substances of different densities by spinning them at high speeds. In this case, when the density of the medium is equal to the density of the particle, there is no density gradient present in the centrifuge tube. This means that there are no density differences to cause the particle to sink or float.
Instead, the particle will experience an equilibrium position within the medium. It will neither sink to the bottom of the centrifuge tube nor float to the top. The particle will remain suspended in the medium, maintaining a stable position within the tube.
This phenomenon is known as isopycnic or equilibrium centrifugation. It is commonly used to separate particles with similar densities or to analyze the composition of complex mixtures, such as isolating organelles or separating DNA fragments of different lengths.
Therefore, if the density of the medium in centrifugation is the same as the density of the particle, the particle will remain suspended in the medium.
