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
The hydrosphere makes up all of earths water, and has a secondary sphere called the cryosphere which encompasses all of Earth’s ice. This is important for all living things. Aquatic life lives in water, and land animals drink it to survive.

Answer:
The first phase of Meiosis 1 is prophase 1. during the prophase 1 is where DNA is exchanged between homologous Chromosomes in a process called crossing over or recombination.
Meiosis does not occur in <span>archaea</span><span> or </span>bacteria<span>, which generally reproduce via asexual processes such as </span>binary fission<span>. However, a sexual process known as </span>horizontal gene transfer involves the transfer of DNA from one bacterium or archaeon to another and recombination of these DNA molecules of different parental origin.
