Thank you for the opportunity to help you with your question!
3. the rate of oxygen demand would be exponential starting from zero demand since the cells were dead. the biological oxygen demand increases exponentially
4. since the two animals have the same body weight a mammal will have a higher respiration rate than the reptile since the reptile temperatures will vary with the environment. a mammal always tries to maintain a constant respiration rate with varying environmental temperatures.
5. at 22 degrees a mammal will have a lesser metabolism than the reptile. reptiles become active at certain optimum temperatures while they become inactive at low temperatures. the metabolism of the reptile becomes higher at these temperatures as they rise from 10-20 while the mammal reduces its metabolism since it doesn't need much temperature to maintain its body temperature at elevated temperature levels
