The answer is <span>B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.</span>

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.
