They only have 23 chromosomes because they go through meiosis instead of mitosis, in mitosis the chromosomes are duplicated so then you have cells with the full 46 chromosomes, however eggs and sperm go through meiosis which doesn’t duplicate the cells because when a sperm (23 chromosomes) and a egg (23 chromosomes) combine then there’s the full 46 chromosomes for the cell.

Calculate the cardiac output if heart rate (HR) is 90 beats per minute, stroke volume (SV) is 110 ml/beat, end diastolic volume
Yakvenalex [24]

ANSWER: None of the above options are correct.

Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)

Therefore where HR= 90bpm and SV= 110ml/min,

CO = 90 × 110 = 9900ml/min or 9.9L/min.

EXPLANATION:

CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.

Cardiac output is the product of two variables, stroke volume and heart rate.

STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.

HEART RATE is the count of the number of times the heart beats per minute.
