B. The air you breathe.
Because the rest of the choices are not environmental factors. Gang activity, and access to jobs and education are not environmental because environment are things about the world.
ANSWER:
Cardiac output(CO) in L/min = stroke volume(SV) X Heart rate(HR)
Therefore,
CO= 100 x 75= 7500 ml/min
CO= 7.5 L/min
EXPLANATION:
CARDIAC OUTPUT is the volume of blood, pumped by the heart, that goes through the systemic circulation every minute. It is determined by the stroke volume and heart rate.
STROKE VOLUME is the volume of blood ejected from the ventricles of the heart in each contraction.
HEART RATE is the number of times the heart beats in a minute.
Answer:
Experience
Explanation:
Little basic experience will do. You don't have to be a pro. Have fun.
