This theory led to a belief in 'earthquake weather', that because a large amount of air was trapped underground, the weather would be hot and calm before an earthquake. A later theory stated that earthquakes occurred in calm, cloudy conditions, and were usually preceded by strong winds, fireballs, and meteors.
Answer:
Human cells can readily absorb folic acid; bacteria cells cannot.
Explanation:
Bacterial cells cannot absorb folic acid and synthesize it. On the other hand, humans do not synthesize folic acid in their cells. They rather obtain it from the diet. Sulfa drugs, for example, sulfanilamide resemble p-aminobenzoate (PABA). PABA is a molecule that is used as a substrate in the synthesis of the coenzyme folic acid. The sulfa drugs serve as competitive inhibitors and compete with PABA for the catalytic site of an enzyme involved in the folic acid synthesis. This prevents the synthesis of folic acid in bacterial cells and thereby, inhibits bacterial growth.

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.
