there is more dissolved oxygen present in a stream because the movement and the bubbling of the air allows more oxygen to be ingested

Does a lake with catfish have more dissolved oxygen than a lake with trout?
yes
Would you expect a fast moving mountain stream or the Mississippi River to have more dissolved oxygen?
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
Which contain the greater amount of dissolved oxygen a lake in the spring or a lake in the summer?
. Temperature directly affects the solubility of oxygen in water. When the temperature of water increases, a portion of oxygen converts from liquid state to a gas. Thus the ability of water to maintain oxygen in dissolved state decreases with increasing temperature. As a result, colder water can potentially contain more dissolved oxygen than warm water. Therefore, a lake in spring contains greater amount of Dissolved Oxygen than the same lake in summer.
Does a lake or a river contain more dissolved oxygen?
the river would contain more dissolved oxygen because the water movements cause more oxygen to be produced...try looking at lab bench..it's like a prelab but it helps with the basic information
Which is more salty stream or lake van?
Stream is not more slty then lake van
Who is more salty stream water or lake van?
Which is more salty water stream or lake van
Where would have more dissolved oxygen a lake containing catfish or one containing trout and why?
i think trout (even if oxygen may not be able to dissolve!) because catfish are able to extract more oxygen because they are larger!
Who has more salty water stream or lake van?
lake van
What happens if there is too much oxygen in seawater?
Oxygen in the water is called "dissolved oxygen" because quite simply it is just that. The air naturally diffuses into the water and can reach equilibrium with the water. It is virtually impossible to get too much dissolved oxygen in the water because the excess will convert back to gas and bubble out of the water like so much soda water when you pour it out of the bottle. This said, there is no concern for too much dissolved oxygen in the water. Concern arises when dissolved oxygen levels get too low. When this happens more sensitive plants and animals become weak or die. As a side note, weather, temperature, and salinity all effect dissolved oxygen levels. Faster moving water contains more dissolved oxygen because it has more contact with the air than still water. Cold, fresh water holds more oxygen than warm or salty water. This would mean a cold, fast moving, fresh water stream or river would contain the highest amounts of dissolved oxygen, and the salinity of the ocean water would not be ideal for holding as much dissolved oxygen.
Why might a tropical lake have more minerals dissolved in than any other lake?
lakes
Which gas is on inhalation dissolved in blood hemoglobin more rapidly than oxygen?
Its an Oxygen.
Would you expect the DO in water taken from a stream entering a lake to be higher or lower than the DO taken from the lake itself Explain?
AP Biology lab book, huh? Lab Twelve... This is lab twelve in the AP Bio course. You can assume that the stream is a stream with a good current, so oxygen will get incoorperated with the water through turbulance. There is more turbulance in a stream than in a lake. This factor will result in higher concentrations of DO in a stream. Also, the overall temperature in a stream is lower because the sun cannot heat moving water as fast as it can heat non-mobile water.Both of these factors will result in a higher DO in the stream than in the lake.
