Answer:

The correct answer is - option 1. 930 kilocalories.

Explanation:

In every ecosystem, the energy is passed from one form to another and there is a lot of loss of the energy as heat in the cellular process. There is a transfer of only 10% of each level of the trophic level.

Algae is the producers in this aquatic ecosystem so the primary consumer will get  10% of the energy that is present in plant tissue (93000kcal) which will be 9300 Kcal and second producers will get 10% of this will be 930Kcal.

Thus, the correct answer is option 1. 930 kilocalories.

Explosions can occur when electricity ignites explosive gases in the air, such as pure oxygen, methane, or natural gas. true or
victus00 [196]

Answer: True

Explosions due to electricity occurs due the passage of electrical current into air, this results in the transfer of energy from electricity to air. Electrical energy   being a stimuli activates the molecules of air which leads to explosion. An explosion is a rapid event which involves release of energy in the form of gases and also destruction of surrounding entities. For explosion suitable fuel and combustion gases are required. Methane and natural gases acts as fuels whereas oxygen which facilitates combustion of these fuels.

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.
