One consequence of CFCS pollution is increased rates of skin cancer in humans.
Cholofluorocarbons cause the breakdown of the ozone layer that protects the earth from the sun's ultraviolet radiation. Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are brojken up by ultraviolet radiation, releasing the chlorine that catalytically destroys ozone.

Answer:
SV = 30 ml/ beat.
HR = 80.
Explanation:
The formula to calculate SV is as follows:
SV = EDV- ESV.
Here EDV = 90ml (end diastolic volume), ESV = 60ml (end systolic volume) ans SV is stroke volume.
SV = 90-60
SV = 30ml/beat.
The formula to calculate HR is as follows:
HR = CO/SV
Here, HR is heart rate, CO is cardiac output = 2,400 ml/min and SV is stroke volume = 30ml/beat
HR = 2,400/30
HR = 80.
Thus, the SV is 30ml/best and HR is 80.
