A gene<span> is a stretch of DNA or RNA that determines a certain trait. </span>Genes<span> mutate and can take two or more alternative forms; an </span>allele<span> is one of these forms of a </span>gene<span>.</span>
The answer is C
<span>Some DNA moves from one cell to another.

A cell can be thought of as a "factory," with different departments each performing specialized tasks.
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
