How can you determine if oxygen levels are high or low?
When oxygen levels are high people tend to get a 'high' sensation. When the oxygen levels are low, it feels like you are going to pass out. There are other ways to tell, but generally you would need prodigious equipment, that is most likely very expensive.
How many electrons does oxygen have in it's first energy levels?
In the very first shell it has 2 and then it has 6 (in the second shell). =)
Carbon and other nonmetals are found in which area of the periodic table?
they are usually found in the top right area of the table (carbon, nitrogen, oxygen, phosphorus, sulfur, selenium) and hydrogen in the very top left
Where and when was oxygen discovered?
Oxygen was discovered by the very first species on planet Earth.
Why is 80 percent of air nitrogen not oxygen?
Nitrogen is relatively inert and so will stay stable in the atmosphere. Oxygen on the other hand, is very reactive and is also in a constant cycle of being removed from the atmosphere by cellular respiration and replenished by photosynthesis. The higher concentration of oxygen in the atmosphere, the more likely it is to react with something, which will deplete the amount. Currently, the air is about 21% oxygen, but has reached levels as high as 35% during different periods.
Is ocean ocean?
A Very Large Expense Area Of The Sea Is Called OceanFor Example!Atlantic Ocean.
Where does the oxygen in the ocean from?
In oceans, Oxygen gets dissolved in a very small proportion from the atmosphere. This process is very gradual. Oxygen also comes from the aquatic plants present in the water bodies.
If the ocean rises fast can humans evolve fast enough to survive?
Evolution is a very slow process, so if the ocean levels rose very fast humans would not evolve fast enough to survive, however they may develop technology to counteract it. It is also very unlikely that the ocean levels will rise that quickly.

How can the oxygen store in myoglobin be replaced after use?
Myoglobin has a very high affinity for oxygen, meaning it binds it very strongly. At very low oxygen concentrations in the cell, myoglobin releases its oxygen, despite the high affinity, simply because there are too few oxygen molecules around to rebind to the myoglobin when they are released naturally from the myoglobin (which usually occurs anyway). Once the oxygen concentration increases again, returning to normal, oxygen molecules will collide with myoglobin. The myoglobin, with its high oxygen affinity, will strongly bind any oxygen that meets it, replenishing myoglobin's oxygen storage very quickly. As myoglobin's affinity for oxygen is stronger the haemoglobin's, it will 'steal' oxygen from haemoglobin in the blood very easily, replacing its bound oxygen. This binding system serves to release oxygen when it is needed if blood oxygen levels are reduced (due to high levels of exercise), but replenishes the supply when oxygen levels begin to rise again.
What is Ocean-Ocean?
A Very Large Expense Area Of The Sea Is Called OceanFor Example!ATLANTIC OCEAN.
Why doesn't other planets have oxygen?
because you need biological life. You also need liquid water. Mars does have oxygen @ very low levels. Other planets do have oxygen.
What major adaptations do bacteria in the ocean have?
the ability to breathe under water with very little oxygen
Does the ocean have low nutrient levels?
The evironment of the ocean is very low-nutrient. This is due to the fact that it is a HUGE environement and none of the ecosystems contained withing (such as coral reefs) can generate enough nutrients to make the entirety of the ocean system contain normal levels of nutrients.
How much light is in the open ocean?
Very much because the open ocean is basically the surface-ish area.
What would happen if salinity levels were drastically changed?
The life in the ocean would change and so would the gravity in the ocean. Therefore salinity is very important.
Do estuaries have a low oxygen level?
Estuaries are marine environments whose Ph , salinity , and water levels vary, depending on the river that feeds the estuary and the ocean from which it derives its salinity Many animals also burrow to avoid predation and to live in the more stable sedimental environment. However, large numbers of bacteria are found within the sediment which have a very high oxygen demand. This reduces thelevels of oxygen levels of oxygen within the sediment often resulting in partially anoxic conditions, which can be further exacerbated by limited water flux.
