Answer:

This is most likely due to a mutation in a maternal effect gene.

Explanation:

The genes of maternal effect are the result of a special genetic inheritance that is managed by genes present only in the mother's body, of a certain individual. These genes are responsible for determining some specific conditions in the egg, generating some changes in the individual's genotype and phenotype. In summary, these genes are responsible for contributing to the phenotype of an individual directly related to the mother's genotype.

Like any gene, genes of maternal effect can mutate, generating some phenotypic anomalies. An example of this is the existence of two tails in an abnormal embryo of Drosophila.

Assume that the left ventricle of a child's heart has an EDV=90mL, and ESV=60mL, and a cardiac output of 2,400 mL/min. His SV is
Sliva [168]

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.
