Which would most likely cause a decrease in numbers of woodpeckers in ecosystem
Blizzard [7]
The answer is: A decrease in the number of Trees

Woodpeckers are known for their use of finding food sources on the trucks of trees. They are also popularly own for beating their beaks against a tree trunk in order to provide vibrations and communicate with other woodpeckers.
Contrary to popular belief, they do not eat wood, but trees as a whole form an important part of their habitat.

Hence, the deforestation, cutting down of trees and urbanization can all lead to the decreasing number of woodpeckers in the ecosystem. 

Since the early 20th Century two species of American woodpeckers are already considered extinct.

Drag and drop the appropriate labels into position to explain how this defect might cause mr. g's other problems.
marissa [1.9K]

How does Mr. G's altered blood flow explain his signs and symptoms? Drag and drop the appropriate labels into position to explain how this defect might cause Mr. G's other problems. Fill the boxes in order, starting with 1, then 2, etc

(Image attached)

Answer:

  1. When left ventricles contracts, some blood goes up through mitral valve into the left atrium, Turbulent flow through the valve causes systolic murmur. the atrium is overfilled and dilated.
  2. Because some blood re-entered the mitral valve, less is pumped out into the aorta. the ejection fraction is only 43%
  3. Less blood enters aorta, so SBP is low. Baroreceptor reflex causes increased heart rate; wall of overworked left ventricles becomes thicker
  4. Because its already partly full of blood from the ventricle, the left atrium accepts less blood from the lungs, the lungs overfilled with fluid; resulting in troubled breathing.

Explanation:

A murmur is a result from a abnormal blood flow to the heart.Its basically an unusual sounds that is heard between heartbeat A systolic murmur occurs when the heart muscles contracts. i.e they begin and end between S1 and S2.

From the above information, it seems like Mr G is experiencing mitral regurgitation. It is a condition where mitral valve doesnt close tightly and as a result the blood flows back from the left ventricle into the left atrium.

larisa [96]

Answer:

The second code in this case is the procedure for perfusion

Explanation:

Extracorporeal perfusion is the process of diverting the patient's blood via an artificial circulatory device to enable the gas exchange (oxygen absorbed, carbon dioxide removed) to take place. Only medical experts should handle this procedure so as to avoid any and all undesired scenarios or negligence towards patient care.
