9) Forensic anthropologists use body temperature and muscle stiffness to estimate when someone died. Use the information in the graph to complete the table below: Condition of body Time since death (provide a RANGE - remember to include units!) Warm, flaccid Warm, stiff Cool, stiff Cool, flaccid *Note: the progression of these phases varies with environmental temperature - a body in cold conditions will cool faster and progress through the phases of rigor mortis more slowly* 10. What happens to oxygen levels in human muscle cells after death? Why? 11. a. What process usually produces ATP in living muscle cells? b. What happens to the rate of this process after death? Why? Relate this back to your answer to question 10. 12. a. In which organelle are calcium ions stored in muscle cells? b. By what process do muscle cells pump calcium ions back into this organelle and keep them there (establish and maintain a concentration gradient)? What does this process require?
