1. What is a chromosome?
 -It is DNA coiled up together.
 2. What happens, as the cell gets larger?
 -The DNA is copied; cell divides because the cell becomes less efficient.
 3. What is asexualreproduction?
 -Offspring from a single parent
 4. What is sexual reproduction?
 -Offspring produced by two parents with genetic information from both of them.
 5. What is cell division?
 -Whencell divides into two new daughter cells.
 6. What is the difference between Prokaryotic cell cycle and Eukaryotic cell cycle?
 -Prokaryotic cell: DNA duplicates and cell divides
 -Eukaryotic cell:Interphase, Mitosis or Meiosis.
 7. What is the difference between Mitosis and Meiosis?
 -Mitosis is asexual and Meiosis sexual
 -Mitosis is not diverse and Meiosis is diverse
 8. What are thephases of Mitosis?
 -Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
 9. What is the difference between Cytokinesis in Animal Cell and Cytokinesis in Plant Cells?
 -Animal cell: the membranedraws inward
 -Plant cell: a cell plate forms.
 10. What are the two types of proteins?
 -Cyclin and Internal/External Regulators.
 11. What are the phases for Eukaryotic Cell Cycle and whathappens in each one?
 -G1: cell growth
 -S phase: DNA replication
 -G2: prepares for mitosis
 -M phase: Mitosis and Cytokinesis
 12. What happens in each phase in the Mitosis cycle?
 13. How is thecell cycle regulated?
 -Cyclin
 14. How are the growth of a tumor and repair of scrape on your arm similar? How are they different?
 - They are similar because they both involve in fast cellreproduction and they are different because for the scrape, they will slow down once it is healed and for the tumor it won’t stop.
 15. What is an Apoptosis?
  - When a cell is programmed to die. 1.  What is the treatment for cancer?
 - The treatment is radiation directed toward the tumor or infected area.
