there is more dissolved oxygen present in a stream because the movement and the bubbling of the air allows more oxygen to be ingested
yes
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
. 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.
Stream is not more slty then lake van
Which is more salty water stream or lake van
i think trout (even if oxygen may not be able to dissolve!) because catfish are able to extract more oxygen because they are larger!
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
lake van
The pH level of a solution can affect the levels of dissolved oxygen. When the pH is lower (more acidic), the solubility of oxygen decreases, leading to lower levels of dissolved oxygen. Conversely, when the pH is higher (more basic), the solubility of oxygen increases, resulting in higher levels of dissolved oxygen.
lakes
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.
Its an Oxygen.
