What is Decreased by the breakdown of organic wastes?
Dissolved Oxygen
What is biological imortance of air dissolved in water?
Oxygen can be dissolved in water. This is biologically important because animals that live in the water, such as fish, need to get oxygen from the water to perform respiration and live.
What produces dissolved oxygen?
A) light reaction alone B) Clavin cycle alone C) both A & B D) neither of both E) Occur in the chloroplast but not the part of photosynthesis
How is oxygen carried through the bloodstream?
Oxygen can travel dissolved in the plasma, but mostly it binds to a specific molecule - hemoglobin - found in red blood cells.
What two major factors do marine organisms depend on for their survival?
They depend on FOOD and DISSOLVED OXYGEN.
How might you account for dissolved oxygen concentrations of such a low value at a temperature of 25C?
Other factors must have caused the low dissolved oxygen levels. Bacteria and other organisms can lower the dissolved oxygen of water when they respire aerobically.
Does a biological oxygen demand value would be a negative value?
The only way a biochemical oxygen demand value could be negative is if oxygen increased in your incubation. This could result from several errors, but most likely light was allowed to penetrate your bottle allowing photosynthesis to occur. If everything was done correctly (e.g. insturments are calibrated and working, no errors were made in calculations) you should have at least a 1mg/L difference between initial and final dissolved oxygen readings yielding a positive value.
Normal ranges for dissolved oxygen test?
dissolved oxygen is dissolved oxygen
What is the oxygen dissolved in water is a?
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
When sodium chloride is dissolved into water what part of the water molecule does sodium get attracted to?
The negative dipole of the oxygen
When calcium chloride is dissolved in water to which end of the adjacent water will a calcium ion be attracted?
The oxygen end, which is the negative pole.
What's dissolved oxygen?
Dissolved oxygen is the current amount of oxygen in the water. A certain amount of Dissolved Oxygen Is needed to keep the fish alive, if any of the dissolved oxygen decreases by either a little or a lot it can cause changes in the water, normally if the dissolved oxygen decreases so do the fish and aquatics life's life.

What is dissoving?
Dissolved Oxygen is the bubbles in water when you splash there's bubbles in the water that is Dissolved Oxygen.
Do you breathe water?
We do not breathe in the water as we can't breathe dissolved oxygen.Dissolved oxygen are oxygen that are dissolved into the water.
How do dissolved gases get in ocean water?
The main dissolved gases found in the ocean include, but are not limited to: carbon dioxide, oxygen, and hydrogen. Dissolved gases, especially oxygen, are important, since it provides dissolved oxygen for aquatic organisms to "breathe" in. Also, the carbon dioxide dissolved in the ocean helps lessen the amount of carbon dioxide in the environment.
