Explanation:
Differentiation in cells occurs due to the silencing of some genes in the DNA of the cell while leaving others open to RNA polymerase enzymes.
Silencing occurs through the mediation of histones that tightly coil up DNA into heterochromatin in some regions. This way the genes in these regions are inaccessible to transcription enzymes and proteins and cannot be expressed. This means that proteins associated with these genes are not produced.
The open genes, on the other hand, in the euchromatin region, produce the necessary proteins that are associated with the determined function of the cell.
An example is that while the hepatocytes cells and brain cells of the same person have the same DNA, the genes for producing bile are silenced in the brain cells (and are open in hepatocytes) while genes responsible for producing neurotransmitters are silenced in hepatocytes but open in brain cells.

Answer: The bubbles will form due to the liberation of oxygen gas and white spots will develop on the liver.
Explanation:
The liver is a vital organ, its function is to metabolize the toxins into less harmful metabolites, that are excreted out of the body.
The catalase is one of the enzymes that participate in the metabolic activities of the liver. In the given condition, when hydrogen peroxide and liver were combined. The catalase enzyme breaks down the hydrogen peroxide into water and oxygen. In this reaction, the oxygen gas is liberated, in the form of bubbles and this reaction produces white colored foam which later leaves white spots on the liver.
