The image shows a cell in one of the stages of mitosis. Which of the following statements correctly describes the stage of mitosis shown in the image?

• The phase shown is anaphase because the copies of each chromosome are separating.

• The phase shown is metaphase because the chromosomes are moving toward the center of the cell.

• The phase shown is interphase because the chromosomes are duplicating their genetic information.

• The phase shown is prophase because the copies of each chromosome are preparing to divide into two daughter cells.

Which of the following statements correctly describes cytokinesis?

• Cytokinesis is the stage of the cell cycle when the cytoplasm of the cell divides, resulting in two daughter cells and takes place at the end of mitosis.

• Cytokinesis is the stage of the cycle when the genetic information is replicated, resulting in two daughter cells and takes place after mitosis.

• Cytokinesis is the stage of the cell cycle when the cytoplasm of the cell divides, resulting in two daughter cells and takes place in the beginning of mitosis.

• Cytokinesis is the stage of the cycle when the genetic information is replicated, resulting in two daughter cells and takes place during mitosis.

Which of the following best describes the difference between meiosis I and meiosis II?

• Meiosis I is responsible for creating four genetically unique cells and meiosis II is responsible for creating four cells that are genetically different from the parent cell.

• Meiosis I is responsible for creating four genetically unique cells and meiosis II is responsible for creating two cells that are genetically different from the parent cell.

• Meiosis I is responsible for creating two cells that are genetically different from the parent cell and meiosis II is responsible for creating four cells that are genetically identical to the parent cell.

• Meiosis I is responsible for creating two cells that are genetically different from the parent cell and meiosis II is responsible for creating four genetically unique cells.

The image shows a cell in one of the stages of cell division. Which of the following statements correctly describes the stage in cell division shown in the image?

• The cell is in prophase of mitosis because the number of chromosomes has doubled.

• The cell is in prophase I of meiosis because the number of chromosomes has doubled.

• The cell is in telophase I of meiosis because the cell is separating and contains replicated chromosomes.

• The cell is in telophase II of meiosis because the cell is separating and contains unreplicated chromosomes.
