Why does the level of dissolved oxygen go down after sunset?
noAnswer:There are several factors that could impact the levels of dissolved oxygen in natural water during the evening and night time. None of these are over riding enough to state that the DO levels would go up or down in all situations:* Cooler temperatures would increase the solubility of oxygen in the water. Oxygen already in the water would tend to stay there. * Temperatures in the water would go down decreasing the activity of any decomposition, slowing the reduction of oxygen levels. * Plants (algae etc.) would stop producing oxygen by photosynthesis* Plants would continue their respiration and consume oxygen * Winds are often calmer in the evening reducing aeration of the water through wave action
Why do rocks get worn down by the rain?
Rocks can be gradually dissolved by naturally acidic rainwater.
What is the name of the process by which water carries dissolved minerals from the upper horizons down to lower levels?
It is called Leaching
How do you get ephedrine out of oxygen tanks?
Bleed of oxygen tank upside down and bucket of water when all pressures released but it in a vise Take monkey wrench and cheater pipe and get down through there
Can earth run out of oxygen?
If we cut down all the tree's it could. Tree's recycle carbon dioxide and turn it into oxygen.

What is the function of a dearator on a steam boiler?
Deaerator removes dissolved oxygen from boiler water. The condensate cascades down a number of perforated trays and its surface area is greately increased. This enables dissolved oxygen to come out. Further bleed steam is supplied to deaerator and due to this the atmosphere is predominantly of steam. So the partial pressure of oxygen above the water level is very very low. When a gas exists above a liquid level, the solubility gas in the liquid depend upon its partial pressure. So oxygen comes out of water. Deaerator outlet water has less than 0.05 ppm dissolved oxygen. This is furthe removed by dizing of Hydrazene (N2H2). =A.D.PALAMWAR
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
When was Down on Sunset created?
Down on Sunset was created in 1991.
What is the relationship between bod and do?
BOD (biological oxygen demand) is a measure of the amount of oxygen needed bymicrobes to break down the organic matter in a sample of water. DO (dissolved oxygen) is the amount of oxygen dissolved in the water. When BOD is high, it means there's a lot of organic contaminants in the water, and the microbes are working overtime to break it down. They use up oxygen while doing this, so when BOD is high, DO is low. When the microbes finish breaking down the organic contaminants, their numbers drop from lack of food (a lower BOD). DO usually goes back up again
How are chemical bonds dissolved?
Chemical bonds are not dissolved they are broken down and compounds becomes dissolved.
What bodies of water have more dissolved oxygen?
Bodies of water that are well-oxygenated, usually have higher levels of dissolved oxygen. These include rivers and streams with fast-moving water, as well as colder water bodies like lakes and oceans. Additionally, bodies of water that are heavily influenced by algal blooms or photosynthetic processes tend to have higher dissolved oxygen levels during daylight hours.
Has a nervous system blood vessels and a long digestive tube that runs down the length of its body It can also absorb dissolved oxygen through its skin what is it?
segmented worm that is the answer
Why is cooler in the highest mountains than down the level of the sea?
because their is less oxygen up in the mountains
How do the lungs get the oxygen to the body?
The air enters through the mouth or the nose and is pulled down through the windpipe into the lungs. From the lungs, the oxygen molecules are dissolved in the alveoli and enter the red blood cells in the capillaries of the lung. From the capillaries, they travel to the heart and push oxygen through the body.
How is oxygen taken in into the body tissue?
At the level of the capillaries, oxygen will diffuse out of the saturated red blood cells down their concentration gradient into the tissues where their concentration is lowest.
My blood oxygen level is 57-60 is this concerning?
My dad is in the hospital right now because his oxygen level was 67%. You should seek medical attention because the low oxygen level can cause brain damage and memory loss as well as begin to shut down your organs. I pray things go well for you.
