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.

Whenever a new drug, device, or food, is developed for use in animals, It has to be approved by the FDA before it can be sold and marketed to the public.

Which substance has a high albedo?
Inessa [10]

Answer:

Which substance has a high albedo? B) White Sand

Explanation:

The albedo is the amount of energy that is reflected by a surface. It is determined by the refletivity of that surface. Albedo can range from 0 (no reflection) to a value of 1 (100% reflection). Generally, dark surfaces have a low albedo and light surfaces have a high albedo. Liquid water is considered to have a low albedo, like dark rock and rich soil.
