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

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
