jekas [21]

Answer:

Assume that the left ventricle of a child's heart has an EDV=90 mL, and ESV=60mL, and a cardiac output of 2,400 mL/min. His SV is _30_ mL/beat and his HR is _80_ bpm.

Explanation:

Calculation can be achieved by using this formula.

Stroke Volume (SV) = End diastolic volume – End systolic volume

Given that  

End diastolic volume = 90

End systolic volume = 60

Calculations

Stroke Volume (SV) = 90 - 60

Stroke Volume (SV) = 30mL / beat

Heart rate can be calculated using this formula:

Heart Rate = Cardiac Output / Stroke Volume

Given that

Cardiac Output = 2400 mL / min

Stroke Volume (SV) = 30mL / beat

Calculations

Heart Rate (HR) = 2400 / 30

Heart Rate (HR) = 80 m bpm

How do chloroplasts multiply?
lana [24]
<span> They contain their own DNA in the form of a circular plasmid which encodes some - but not all - of the molecules needed for chloroplast function.. It is theorized that this is the DNA from the free-living photosynthetic prokaryote that became an endosymbiont and then an organelle. This theory, The Endosymbiotic Theory, is widely accepted as a plausible explanation for the evolution of organelles. </span>
