During an acute mi, there is ischemic damage to the heart muscle. the location and extent of the ischemic damage is the major predictor of complications, ranging from cardiac insufficiency to death, following an mi. what is the "window of opportunity" in restoring blood flow to the affected area so as to diminish the ischemic damage to the heart and maintain the viability of the cells?

During an acute myocardial infarction (MI), there is ischemic damage to the hear muscle. The location and extent of the ischemic damage is the major predictor of complications ranging from cardiac insufficiency to death, following an MI. What is the "window of opportunity" in restoring blood flow to the affected area so as to diminish the ischemic damage to the heart and maintain the viability of the cells?

A. 10-20min

B. 30-40min

C. 20-40min

D. 10-30min

The ANSWER is C. 20-40min

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
