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.

Mrac [35]

Answer:

Genus = Elephas

Species = maximus

Explanation:

Carolus Linnaeus, who is considered to be the FATHER OF TAXONOMY for his immense contribution to the classification of living organisms. Carolus Linnaeus between the year 1735 and 1758, developed a scientific system of naming organisms using two-way naming system called BINOMIAL NOMENCLATURE.

The two Latin names given to organisms were derived from their generic and specific epithet i.e. one of the names is GENUS and the other SPECIES. According to this question, the scientific name using the binomial naming system for Indian elephant is Elephas maximus. This means that Elephas is the part that refers to GENUS while maximus is the part that refers to SPECIES.
