Answer: No

Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the material in the cell into two smaller volumes?

Explanation: The cyclin concentration is not halved but degraded during mitosis.

There is an increase in cyclin concentrations at interphase. These changes are caused by the presence of Cyclin Dependent Kinase (CDK) complexes. CDK being a substrate of cyclin catalyses cyclin, thereby increasing its concentration. During mitosis, cyclins are destroyed, signifying the end of mitosis and cytokinesis.

Without this process, it will be impossible for the cell to exit mitosis.
