Approximately all characteristics are inheritable but some characteristic of our body is affected by the external environment.
<h3>Growth:</h3>

<h3>Immunity:</h3>
Immunity is the property of living organism to fight against the harmful agents that invade the body.

Answer:
Normal left ventricle ejection fraction ranges from 55% to 70%
Explanation:
Ejection fraction depicts that with each heart beat, how much amount of blood is pumped by the left ventricle with each contraction as left ventricle is called as the main pumping chamber.
The percentage below EF value is the sign of heart failure.
The percentage of Normal Left Ventricle ejaculation fraction (LVEF) is 55% to 70% and if the value goes down, then it can create hear failure.
If the value is between 40% to 54%, that means less blood is ejaculated by Left ventricle as the amount of availability of blood is less.
If the percentage of EF value is below 35% that will determine the great risk of life threat for irregular heart beat.
Im not to sure but i thinks its pulmonary vein
