Answer: The correct answer is B) The regulation of gene expression within each cell type.

The body of an organism is made of cells, which possess same number of chromosomes ( like 46 chromosomes in all human cells) with the same complement of genes. This means that all the specials ed cell ( performing specialized function in the body) like bone, muscle, nerve cells contain the same number of chromosomes.

The difference in their activities/ functions is primarily because of differential expression of genes. In other words, different genes are transcribed and translated in different cells resulting in the formation of different proteins. This enables them to perform different functions.

Thus, the regulation of gene expression within each cell type enables them to perform differently.

What makes the same cells perform specialized activities is differentiation.

What is cell differentiation?

Cell differentiation is a process whereby cells become specialized for specific functions.

Specialization for specific function is what makes cells of the same origin develop into different tissues, organs, or systems in the same organisms.

Cells that are not specialized for specific functions are called stem cells.
