Answer: in the above example, cancer is an independent variable.
Explanation:
Based on the information given, we can infer that the dependent variable is cancer. Cancer is not the independent variable.
The extent to which an individual smokes is.an independent variable, duration of smoking, smoker's age can all be identified as the independent variable.
Cancer is not a independent variable here, in our study cancer is dependent on the amount of smoking by an individual.So, it is a dependent variable.
Answer:
Yes, the blood pressure and heart rate return to normal after 5 minutes of physical exercise as, ANS will detect the decreasing level of oxygen and activate parasympathetic system to normalize the heart rate. The increasing of heart rate does not cause the blood pressure to increase at the same rate. After 5 minutes it return to normal as when you exercise heart rate speed up so that is why more blood reach in the muscles so it cause high heart rate and blood pressure for some minutes.
Answer:
Rate = 6,120 - 8,160 ml
Explanation:
Given:
Total mass = 85 kg
Per breath tidal volume = 6-8 ml/kg
Rate of breath = 12 breaths per minute
Find:
Breath rate tidal volume in 1 minute.
Computation:
Rate = Total mass × Per breath tidal volume × Rate of breath
Lower limit = 6
Lower rate = 85 × 6 × 12
Lower rate = 6,120 ml
Higher limit = 8
Higher rate = 85 × 8 × 12
Higher rate = 8,160 ml
Rate = 6,120 - 8,160 ml
