The ratio of surface area to volume affects the cell when it comes to the exchange and movement of materials. If the cell would get larger, getting sufficient oxygen and nutrients, as well as expelling waste would be very difficult to sustain. Therefore, the number of nuclei is irrelevant to the ratio of surface area to volume.

C. number of nuclei

Cyclin is a protein found in cells under mitosis. This protein is mainly responsible for the timing of the cell cycle and it triggers the cell division.

E. cyclins

The four stages of mitosis include prophase, metaphase, anaphase, and telophase. Interphase occurs before mitosis.

E. interphase

Two sister chromatids, which are the identical parts of a chromosome, are joined together at the centromere.

C. centromere

Interphase is the stage that occurs between cell divisions. This is the stage of cell growth, DNA replication, and the preparation for cell division. Once the cell has gone through interphase, it is now ready for mitosis.

Cancer, which is considered the disease of the cell cycle, is a disorder that is characterized by an uncontrollable cell growth. Cancer cells fail to respond to any external regulator and internal regulator that ensure an orderly cell growth. As a result, the loss of growth control breaks down the normal cell cycle.

D. Cancer

Cytokinesis is the process of cell division wherein the cytoplasm of a parent cell divides into two equal parts.

C. Cytokinesis

The cell cycle is defined as the series of events that take place during cell growth and division. The main events of a cell cycle include the interphase and mitosis. Interphase consists of the G1 phase, which is the stage of cell growth; the S phase, which is the stage for DNA replication; and the G2 phase, which is the preparation for cell division. After interphase, mitosis occurs. It is the division of a parent cell into two daughter cells. In turn, each of the two daughter cells will undergo the same cycle again.

B. Cell cycle

Mitosis is the cell division or the splitting of a parent cell into two daughter cells. The four stages of mitosis include prophase, metaphase, anaphase, and telophase.

A. Mitosis

The experiment shows how chromosomes migrate during cell division. It shows how the chromatids got separated and how the chromosomes were moved apart.

Since the laser beam didn’t inhibit the normal function of the spindle fibers, there are no changes in length or size on either side of the mark.

E. do not change in size on either side of the mark.

As shown in the evidences of this experiment, the sister chromatids are separated and pulled towards the centrioles that are located on the opposite poles of the cell.

A. centrioles pull chromosomes toward the poles of the cell.
