An oxygen saturation level of 82% is considered low and may indicate a significant issue with oxygen delivery to your tissues. This could result from conditions such as respiratory diseases, heart problems, or low hemoglobin levels. It is crucial to seek medical evaluation promptly to determine the underlying cause and receive appropriate treatment.
Oxygen has 8 electrons, so it will have 8 energy levels.
The limit for dissolved oxygen in Water for Injection (WFI) is typically less than 0.1 ppm (parts per million). High levels of dissolved oxygen can promote oxidation and microbial growth, so it is important to keep oxygen levels low in WFI to maintain its quality and stability for pharmaceutical use.
Oxygen levels do not actually decrease with fading daylight. However, during photosynthesis, plants produce oxygen when exposed to sunlight. So in the absence of sunlight at night, the production of oxygen decreases. This might give the impression that oxygen levels go down when daylight fades.
Cytosis, or cellular transport, is a process that involves the movement of molecules across a cell membrane using energy. Changes in oxygen levels can affect the rate of cytosis because oxygen is essential for cellular respiration, which provides the energy needed for active transport processes involved in cytosis. Diffusion, on the other hand, is a passive process that relies on the random movement of molecules from an area of high concentration to an area of low concentration, so changes in oxygen levels do not directly impact diffusion.
Oxygen stays as diatomic molecules in the atmosphere. These 2 oxygen atoms are bond with a double bond. So reactivity of oxygen is low.
Oxygen has 8 electrons, so it will have 8 energy levels.
A faculatative anerobe does NOT require oxygen for growth but may use if available so it can grow in aerobic and anaerobic conditions. Too much oxygen is NOT toxic. A micro-aerofile CAN'T grow without oxygen but too much oxygen is toxic so it must have a low concentration in order to grow.
Oxygen is used to metabolize carbohydrates and produces carbon dioxide. In addition an increased rate of respiration will lower carbon dioxide levels while increasing oxygen concentrations to saturation. Despite this they are two independent parameters. If someone were to be at a high altitude they could have almost no C02 in their blood, be breathing rapidly and have low oxygen levels. Similarly carbon monoxide will bind strongly to hemoglobin so that oxygen levels will go down, but since except at very low levels of oxygen, breathing will remain unchanged as CO2 levels, which drive the rate of respiration normally will be unchanged.
Oxygen level should be in the upper 90's.... My son is on a machine so we can watch it regularly and the alarm goes off if he dips to 90.
Oxygen is very vital for your survival. So you tend to think that low oxygen is a powerful stimulator for the respiration. But then, this is not correct. Oxygen is very sparingly soluble in the water or plasma. So oxygen is not used to regulate the respiration. Instead, the carbon bi oxide is highly soluble in water or plasma and the same forms the acid after dissolution. So the concentration of the carbon bi oxide can be easily measured by the respiration centre cells of your brain. That is why the concentration of carbon bi oxide is the stimulating or suppressing factor in case of the respiration. Increase in carbon bi oxide concentration stimulates the respiration and vise verse.
When you don't get enough oxygen to your blood, your body may start to show symptoms like shortness of breath, confusion, or bluish lips. It is important to seek medical help immediately, as low oxygen levels can be serious and potentially life-threatening. In a medical setting, supplemental oxygen may be provided to help increase oxygen levels in the blood.

Both oxygen and nitrogen are equally important to living things. Oxygen is necessary for metabolism to continue. But too much oxygen is poisonous. So the presence of nitrogen keeps the oxygen levels low enough to avoid poisoning.
As has been proven so many times in a wide variety of places Algae will grow anywhere it can regardless of local conditions
Ans: Less than ~8%.....During sleep the requirements are the least so you could last longer. Air is made up of ~20% oxygen...going to an altitude of 10kft its important to have added oxygen to prevent hypoxia.

Nitrate levels are low in waterlogged soil because the lack of oxygen in waterlogged conditions impedes the microbial processes responsible for converting nitrogen into nitrates. This limits the transformation of organic nitrogen into nitrate form through nitrification.
