15. 12. What is cytokinesis? A. Dividing the nucleus B. Replicating the DNA C. Split the parent cell into two daughter cells D. Makes the cell bigger.

16. 13. Which is the chromatids? Type the answer here. A B C

17. 14. Which is the centromere? Type the answer here. A B C

18. 15. Which is the sister chromatids? Type the answer here. A B C

19. 16. What happens in cancer cells? A. The DNA mutates and is passed along to the daughter cells. Division happens rapidly and cancer spreads. B. The daughter cells do not divide. C. The parent cell does not divide. D. One daughter cell is bigger than the other daughter cell.

20. 17. What is homeostasis? A. Regulation of the internal environment of an organism B. How your body functions C. Regulation of the external environment of an organism D. How organisms survive

21. 18. What is one topic that helps to maintain homeostasis? Bonus if you can name the other two A. Maintaining blood sugar B. Structure and function C. Cell Division D. Temperature

22. 19. What do spindle fibers do (orange yarn)? A. Pull apart sister chromatids to opposite ends of the cell B. Breaks the centromeres of the sister chromatids C. Condenses chromosomes D. Breaks the cell into two cells

23. 20. Explain one way homeostasis works. Could talk about how body regulates glucose, sweat, or water Could talk about structure function, division of labor, and interdependence of organ systems. Ex: Body gets to hot= sweat to cool you down; Body gets cold= shiver to keep warm, blood circulates towards the center of body the best
