If there is a total of one liter of nitrogen gas dissolved in the body tissues at sea level how much would be dissolved in a diver breathing air at 99 feet below the sea after the tissues has equilib?

The tissues do not "equilib." Your body builds up more and more nitrogen until there is so much built up that you get Nitrogen Narcosis, and as you ascend you can (and if at depth way too long, will) have nitrogen bubbles form in your bloodstream. Also known as "The Bends"
That answer is not correct. Tissues do come into an equilibrium state known as saturation (just ask a saturation diver that does not incur longer decompression after being "saturated"). After a certain period of time (the exact time is up for debate), the body has absorbed (or released) all the inert gas (i.e. nitrogen) it can at that steady state depth. The answer to the question can be kept simple with an answer of 4 liters (due to being at 4 times greater pressure than the surface pressure), or complicated by taking into consideration the concepts such as partial pressure vacancy (a.k.a. inherent unsaturation or oxygen window) as well as other gasses not having a linear affect depending on the depth - which would then affect the nitrogen partial pressure or potential uptake. The answer was also not correct as to how nitrogen narcosis works as that is based on actual partial pressure and is not dependent on time.

Which gas diffuses fastest in and out of body tissues?
Nitrogen
Does nitrogen move in cycle?
Yes there is a Nitrogen cycle. 1) Nitrogen in the air 2) Nitrogen in the ground 3) Nitrogen in living tissues (protean) Nitrogen moves through these 3 places as a result of natural (lightening) and biological processes.
How is breathing different from tissue respiration?
Breathing is the physical contraction of muscles such as the internal and external intercostals that draw air into and out of the lungs. Tissue respiration involves the tissues using Oxygen brought to them in the blood and respiring to produce CO2.
How are the gases carried around the body?
Other than as free gases in the lungs, gases are either dissolved in the blood plasma or absorbed by the protein hemoglobin found in red blood cells. Hemoglobin mostly absorbs oxygen, carbon monoxide, or carbon dioxide and carries these gases between the cells and the lungs. Nitrogen gas dissolves in blood plasma and body tissues, and is also a metabolic byproduct (as urea).
Gas is carried mostly by the plasma?
Gas is carried mostly by the plasma in the blood. The plasma contains dissolved gases such as oxygen and carbon dioxide, which are transported to different parts of the body. Oxygen is transported from the lungs to the tissues, while carbon dioxide is carried from the tissues back to the lungs for elimination.
If there is a total of one liter of nitrogen gas dissolved in the body tissues at sea level how much would be dissolved in a dever breathing air at 99 feet below the sea?
It depends. Every 33 feet you go down below the surface is another "atmosphere" meaning another atmosphere of pressure. So if your body is taking in X ammount of nitrogen at the surface, you would be taking in 4 times that ammount at 99 feet. So with nitrogen being taken in that much faster your body builds up a lot of nitrogen very quickly!
Why is the nitrogen we breathe in not absorbed by the blood vessels?
The Nitrogen we breathe IS absorbed by the blood vessels (and all the body tissues). While the Nitrogen gas from the air is inert and does not play any part in body processes, Henry's gas laws require that some of the Nitrogen will be absorbed/dissolve in the blood (and body tissues). This becomes an issue for sub aqua divers where the presence of this dissolved nitrogen causes the "bends".
Which gas diffuses fastest in and out of body tissues?
Nitrogen
When divers dive what gas accumulates in their blood and tissues?
Nitrogen
How much nitrogen gas would be dissolved in a diver breathing air at 99 feet below the sea after the tissues has equilibrated with the higher nitrogen pressure?
This is potentially an involved question. For a simple answer, it would be four times the amount of a non-diver at sea level. The "amount" cannot really be quantified and the only way to answer this is in terms of what the partial pressure of nitrogen would be. But this too gets complicated since partial pressure assumes the gas stays in solution and no bubbling occurs. The next simplistic answer is to multiply the ambient pressure (4 atmospheres or 58.8 p.s.i.) times the nitrogen pressure percentage (79%) to reach an answer of 46.4 psi for the nitrogen partial pressure. But in reality the body is absorbing less than 79% nitrogen due to the water vapor pressure in the lungs, etc.
Does nitrogen move in cycle?

How do you die from the bends?
"The bends" is a slang term for Decompression Sickness. When breathing compressed air at high pressures for extended times, nitrogen gas is forced into the blood. When the pressure is released, the dissolved gas appears as bubbles (like the carbon dioxide bubbles in a soda). The bubble accumulate at joints, causing severe pain, making you curl up (bend) In severe cases, the bubbles can damage the brain, causing a stroke- and death.
Why do organism require nitrogen?
to build tissues and carry out essential life functions
What makes up the respiratory apparatus system?
group of organs and tissues that permits breathing
What is cryogenic surgery?
The selective exposure of tissues to extreme cold, often by applying a probe containing liquid nitrogen, to bring about the destruction or elimination of abnormal cells/ cancer.
What elements make up the tissues of your body?
The body is made up mostly of organic tissues, which are typically composed of carbon, hydrogen, oxygen, and some nitrogen and sulfur.
What are vessels that carry water and dissolved substances from roots to other parts of the plant?
These are the vascular tissues called xylem.
