When the mutation is more beneficial compared to the current alleles
When a person is sleeping, the body moves into 5 different stages which is characterized by a Rapid Eye Movement and a Non- Rapid Eye Movement sleep. The body usually spends 90 minutes in each of the stages. First stage is called the Transitional Phase, second stage is called a Non Rem phase, stages 3 and 4 are known as the deep stages of sleep and the 5th stage is the only Rapid Eye Movement.
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.

<span>The primary distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA/protein structures called ribosomes, which produce protein. Prokaryotic cells are usually much smaller than eukaryotic cells. Therefore, prokaryotes have a larger surface-area-to-volume ratio, giving them a higher metabolic rate, a higher growth rate, and as a consequence, a shorter generation time than eukaryotes.</span>
