Once hooked on the line, they are ensnared in the gear and soon drown. Other fishing practices can also incur large amounts of bycatch. Trawling can drown turtles that get caught in nets. Gillnets are staked to the ocean ...

Some kinds of fishing gear can be even more destructive when they become lost or forgotten in the water because they continue to catch animals, a phenomenon known as “ghost fishing.” This is particularly wasteful and destructive because the gear can ensnare tons of animals that aren't being harvested or used in any way. Fishing piers can be sites of ghost fishing as lures and lines become wrapped around pilings, where animals swimming by become trapped.Fish are not the only victims, however, as birds that dive into the water for prey can also get caught in the lines when they enter the water.

bonufazy [111]

Answer:

The longitude of the location of the ship is W

Explanation:

Here we have the time at the prime meridian as 2 pm while the time at the ship is 10 am. What this means is that the prime meridian is 4 hours ahead of the time of the location of the ship. Geographically, whenever a location is east of the prime meridian, it is ahead of the prime.

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

Answer:

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.
Because some blood re-entered the mitral valve, less is pumped out into the aorta. the ejection fraction is only 43%
Less blood enters aorta, so SBP is low. Baroreceptor reflex causes increased heart rate; wall of overworked left ventricles becomes thicker
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.
