Biology ACP Review Day 3

Multiple Choice

5A: Scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries. This bioengineered tissue is grown from living cells. The cellular process that enables the cells to grow and develop into tissues is:

• Conjugation

• Meiosis

• Budding

• Mitosis

Multiple Choice

During which phase does DNA replication occur?

• G1

• S

• G2

• M

Multiple Choice

Arrange the stages in order.

• I, II, III, IV, V, VI

• VI, II, I, IV, V, III

• III, VI, I, IV, II, V

• V, III, IV, I II, VI

Multiple Choice

What part of the cell cycle results in daughter cells?

• Mitosis

• Prophase

• Cytokinesis

• G2 checkpoint

Multiple Choice

Cells pass through the G2 checkpoint before entering mitosis. Ideally, if DNA damage is detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage repaired before the cells enter mitosis?

• so that another round of DNA synthesis does not have to take place

• so that the chromosomes can align at the metaphase plate during mitosis

• so that the cytoplasm can be divided equally between the two daughter cells

• so that healthy daughter cells are produced, allowing the organism to continue growing

Multiple Choice

In this photomicrograph of an onion root tip, what phase of mitosis is cell A in?

• Anaphase

• Interphase

• Prophase

• Telophase

Multiple Choice

Cancer cells divide uncontrollably because of a failure in

• Protein replication

• glucose absorption

• photosynthesis

• the cell cycle

Multiple Choice

5C: Oncogenes are mutated forms of genes. Oncogenes can transform a cell into a tumor cell. Some tumor cells are benign, while others are malignant. How does the presences of an oncogene lead to the transformation of a tumor?

• ATP production is inhibited

• Cell division is unregulated

• Somatic cell growth is inhibited

• Antibody activity is unregulated

Multiple Choice

Cancer is caused by

• Out of control DNA replication

• Out of control cell cycle caused by damaged DNA

• Out of control cell cycle caused by cyclins

• Tumors

Multiple Choice

All of your cells have the same

• protiens

• carbohydrates

• microbes

• DNA

Multiple Choice

Stem cells are

• cells that grow uncontrollably.
• undifferentiated and can develop into many types of cells.
• cells that never go through cell division.
• only found in embryos.

Multiple Choice

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• genetic engineering
• survival of the fittest
• differentiation
• selective breeding

Multiple Choice

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

• Muscle cells are produced by the brain, but blood cells are produced by the heart. 
• Different genes are activated in muscle cells than in blood cells. 
• Muscles cells experience different environmental influences than blood cells. 
• A mutation occurs during the development of muscle cells but not in blood cells.
