The Skin, arteries, veins, heart all represents the organs of the human body.

Answer: Option B

<u>Explanation:</u>

Human body is an embodiment of many cells that make up the entire new organism. Several cells join together and form a tissue, several tissues join together and form an organ, several organs join together and form an organ system.

The structures with similar function join together to form an higher construct. Similarly the above mentioned structures are organs that would combine with other organs to form an organ system. So the given parts of human body is considered as organs here.

Sound quality can be divided
iris [78.8K]
Sound quality can be divided into amplitude, timbre and pitch. If there’s an impedance mismatch between your two devices connected to the single output, you could have a large mismatch between the levels arriving at each device. If the difference is large enough, one device may have distorted or inaudible audio.

To avoid this, you should ensure that both devices connected to the split signal are similar - such as 2 pairs of headphones, 2 recorder inputs, and so on. When you place 2 devices with wildly differing load impedances on a splitter is when you’ll encounter problems - such as headphones on one split and a guitar amp input on the other.

To get around this, you can use either a distribution amplifier (D.A.) or a transformer balanced/isolated splitter - which will work over a larger range of load impedances, typically. Depends on the quality of the splitter and the exact signal path. If you’re using the splitter to hook two things into one input, and you’re using quality connectors, you probably won’t lose much quality. There can be an increase in impedance of the cable due to the imperfect continuity of the physical connection, however with unbalanced line-level signals, impedance at both ends of the chain tends to be orders of magnitude higher than the connection will create, so one split will be barely noticeable. So too, the noise increase from the additional length of cable.

Now, one source into two inputs, that will by basic math and physics result in a 3dB drop in signal strength, which will reduce SNR by about that much. By splitting the signal path between two inputs of equal impedance, half of the wattage is being consumed by one input and half by the other (the equation changes if the inputs have significantly different impedances). So each input gets half the wattage produced by the source to drive the signal on the input cable, and in decibel terms a halving of power is a 3dB reduction. Significant, until you just turn the gain back up. The “noise floor” will be raised by however much noise is inherent in the signal path between the split and the output of the gain stage; for pro audio this is usually infinitesimal, but consumer audio can have some really noisy electronics, both for lower cost and because you’re not expected to be “re-amping” signals several times between the source and output.

What prevents blood movement from left ventricle to left atrium​
irina1246 [14]

The Mitral valve which is also known as left atrioventricular prevents blood movement from left ventricle to left atrium.

Explanation:

  • Human heart is four chambered.
  • Two of these are receiving chambers known as atria and the other two are distributing chamber known as Ventricles.
  • Atria are superior chambers and ventricles are inferior chambers.
  • The heart has four valves broadly grouped as Atrioventricular valves and Semi lunar valves.
  • Atrioventricular valves allows flow of blood from atria to ventricle. These are tricuspid valve and bicuspid valve.
  • Semi-lunar valves allow blood to pass out of the heart. These include the pulmonary and aortic valves.
  • The pulmonary valve allows blood to flow from right ventricle  to the heart while aortic valve allows blood to flow from left ventricle to the Aorta.
  • The Tricuspid valve located between the right atrium and right ventricle allows blood to flow from right atrium to the right ventricle.
  • The Bicuspid valve ( Mitral valve)  located between the left atrium and left ventricle allows the blood flow from left atria to left ventricle.
  • Valves maintain the unidirectional flow of blood and thus prevent its back flow.

Pls help!!! osmosis help needed!!
galina1969 [7]

Answer:

1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic

Explanation:

1. Given the image, it shows there is 10% glucose outside the cell.

2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)

3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.

2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water <em>outside </em>the cell than in. So, yes, osmosis will occur.

3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).

3. The cell will swell, since water is getting moved in.

6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always <em>swell, </em>as water moves into it.

Hopes this helps!^^ I tried the best I could at explaining.
