12. Necrosis vs. apoptosis

13. DVD clip 77

14. Caspase cascade occurs during apoptosis

15. Procaspase is activated by an active caspase

17. 4 types of intercellular signaling

19. An animal cell depends on extracellular signals to survive or divide

20. An animal cell depends on extracellular signals to differentiate. Without extracellular signals the cell will die

24. Platelet derived growth factor was the first mitogen isolated stimulates cell division during wound healing
