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.
Answer:
B
Explanation:
We breath in oxygen, and we breath out carbon dioxide. Plants breath from the sun.
I really hope this helps!
The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation.
Due to global warming, the climatic conditions such as rise in temperature of the coral habitat in the oceans changes. The corals become stressed by changes in conditions. Under these conditions, corals expel the symbiotic algae living in their tissues. This turns corals completely white. This is called coral bleaching. Due to coral bleaching, it becomes more stressed and this can leads to its death. Algae also may not be able to survive alone.
Post-traumatic stress disorder
Eye movement desensitization and
reprocessing (EMDR) is a form of psychotherapy primarily used for treatment of post-traumatic
stress disorder. This form of treatment helps trauma victims to remember distressing
past encounters and to acquire new understanding of the events.
