Fully-grown adults are much larger in size than young children. What happens to the cells of the body during the growth of a child?

• The cells of a growing child divide to make more cells, and those cells are each half the size as the cells were before they divided. The cells do not grow before they divide again.

• The cells of a growing child divide to make more cells, and those cells grow to become the same size as the cells were just before they divided.

• The cells of the body of a growing child grow, but the number of cells stays the same.

• The size and number of cells in the body of a growing child stay the same.

A student observes a typical onion root tip. Some cells have completed mitosis, and some cells have not. Which statement best explains why some cells have twice as many chromosomes compared to other cells?

• The chromosomes of all cells have replicated, but no cells have undergone mitosis.

• The chromosomes of all cells have replicated, but some cells have not undergone mitosis.

• The chromosomes of all cells have replicated, and all cells have undergone mitosis.

• The chromosomes of all cells have not replicated.

Cell cycle checkpoints are proteins that monitor and regulate the progress of the cell cycle in eukaryotic cells. What would most likely happen if a cell goes through mitosis without completing interphase?

• The new cells would have all of the organelles except the nucleus.

• The new cells would have all of the organelles except the mitochondria.

• The number of chromosomes in the daughter cells would be the same as the number of chromosomes in the parent cell.

• The number of chromosomes in the daughter cells would be different from the number of chromosomes in the parent cell.

A young dog had a broken leg. Which explanation best describes how the dog’s leg healed?

• The dog’s cells went through repeated cycles of the model shown in Figure 1 to repair the broken bone.

• The dog’s cells went through repeated cycles of the model shown in Figure 2 to repair the broken bone.

• The dog’s cells went through one cycle of the model shown in Figure 1 to repair the broken bone.

• The dog’s cells went through one cycle of the model shown in Figure 2 to repair the broken bone.

Nerve cells and bone cells are specialized cells that descend from the same single cell (fertilized egg). Which statement best describes how each type of cell results in a different structure with a specialized function?

• Nerve cells and bone cells begin with the same structure; however, bone cells harden over time.

• Nerve cells and bone cells receive different DNA that determines the structure and function that each will perform.

• Nerve cells and bone cells receive the same DNA; however, only specific parts of the DNA are activated in each cell.

• Nerve cells and bone cells receive the same DNA; however, bone cells receive more to make the protective outer covering.

Skin cells and muscle cells are specialized cells that descend from the same single cell (fertilized egg). Which statement best describes how each type of cell results in a different structure with a specialized function?

• Skin cells and muscle cells begin with the same structure; however, muscle cells stretch over time.

• Skin cells and muscle cells receive different DNA that determines the structure and function that each will perform.

• Skin cells and muscle cells receive the same DNA; however, only specific parts of the DNA are activated in each cell.

• Skin cells and muscle cells receive the same DNA; however, skin cells receive more to make the protective outer covering of the body.

A liver cell can make enzymes that a heart cell cannot make because liver cells

• digest large, complex molecules

• contain more DNA than heart cells

• use different genes than the heart cells use

• remove carbon dioxide from blood

Which best explains why muscle cells are different from blood cells?

• A mutation occurs during the development of muscle cells but not in blood cells.

• Different genes are activated in muscle cells than in blood cells.

• Muscle cells experience different environmental influences than blood cells.

• Muscle cells are produced by the brain, but blood cells are produced by the heart.

How do different cell types arise from genetically identical embryonic cells?

• Different cells in the embryo contain completely different genes.

• Fertilization results in new gene combinations, which result in the different cell types.

• Mutations in embryonic cells result in new genes, resulting in the different cell types.

• Different cells have the same genes, but the same genes aren’t expressed in all cells.
