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 4 factors that affect the steps of the water cycle are tempersture, humidity, windspeed, and solar radiation.

<em>Ossification is a process in which the mesenchymal cells and cartilages convert to bone during development. it is has two types: Membranous and endochondral ossifications. It occurs in mesenchyme which has formed a membranous sheath (figure 4) .</em>
Answer: a,b,c,d
Explanation:
all four of them are characteristics in all living organisms. All living things will grow and change, it will move otherwise it wouldn’t be able to get the nutrients it may need (or run away from predators), in order for the species to go on, they must reproduce, and they must maintain homeostasis so that they don’t freeze of burn to death. but however, it is not required for the living organism to be made up of only one cell, take humans for example.
