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.
The answer is the occipital lobe of the brain
The test tube will be most likely the one with yellowish color.
This happen because of the respiration process between the snail and Elodea. Actually, this will heavily affected by the control factors. The more elodea that exist in the incubation, the lower the amount of CO2 would be,
