The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.
        
             
        
        
        
Answer:
Exponential growth and a type II survivorship curve
Explanation:
- Firstly we need to understand what exponential growth is, it is the type of growth in which population of any specie increases at a tremendous rate, constantly. In this type of growth, the increase is an exponential function of time for example, 2 reproduce to form form, four to sixteen and so on.
Population survivorship curves are simply the graphs representing increase in population with respect to time. There are three types of population survivor ship curve, Type I, Type II and Type III.
- <u>In Type II survivorship curve,</u><u> </u>there is a constant dying rate of individuals of population with respect to time.
Now lets come back towards question, where two characteristics of the population are mentioned,
- Exponential growth of a population of sparrows with each generation.
-  Constant dying rate
<em>This clarifies that </em><u><em>Exponential growth and a type II survivorship curve</em></u><em> is the best option representing the said scenario.</em>
