it can't be negative but can be zero
Dissolved Oxygen
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.
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
Oxygen can travel dissolved in the plasma, but mostly it binds to a specific molecule - hemoglobin - found in red blood cells.
They depend on FOOD and DISSOLVED OXYGEN.
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.
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.
dissolved oxygen is dissolved oxygen
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
The negative dipole of the oxygen
The oxygen end, which is the negative pole.
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.

Dissolved Oxygen is the bubbles in water when you splash there's bubbles in the water that is Dissolved Oxygen.
We do not breathe in the water as we can't breathe dissolved oxygen.Dissolved oxygen are oxygen that are dissolved into the 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.
