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.
Answer:
B. Cells in Alex’s body underwent mitosis to create new tissue
Explanation:
Mitosis is the cell division that forms two genetically identical daughter cells from one parent cell. It occurs in somatic cells and is responsible for the growth and development of individuals.
Alex gained the height as the cells in tissues of his body underwent the mitosis and produced new daughter cells. Repeated cycles of mitosis added a large number of new cells to his body to form new tissues in his body parts and caused an increase in his height.
