Question

the process by which cells become specialized is called
differentiation.
mutation.
cytokinesis.
distinction.
determination.

Explanation:

To solve this, we analyze each option:

• Differentiation: In biology, cell differentiation is the process where cells become specialized in structure and function.
• Mutation: Involves changes in DNA sequence, not cell specialization.
• Cytokinesis: Is the division of the cytoplasm during cell division, not related to specialization.
• Distinction: A general term for difference, not a biological process for cell specialization.
• Determination: Sets a cell on a path to specialization, but differentiation is the actual process of becoming specialized.

So the correct term for cells becoming specialized is differentiation.

Answer:

A. differentiation.
